The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients and minerals from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion. The small intestine is about 20 feet (6 meters) long and folds many times to fit in the abdomen. Although it is longer than the large intestine, it is called the small intestine because it is smaller in width. Small intestine

Anatomical terminology
The small intestine has three distinct regions – the duodenum, jejunum, and ileum. The duodenum, the shortest, is where preparation for absorption through small finger-like protrusions called villi begins. The jejunum is specialized for the absorption through its lining by enterocytes: small nutrient particles which have been previously digested by enzymes in the duodenum. The main function of the ileum is to absorb vitamin B 12, bile salts, and whatever products of digestion were not absorbed by the jejunum. Contents

 A pyloric sphincter prohibits backflow from the small intestine into the stomach. The functions of the stomach are to store food as it is mechanically churned with gastric secretions, initiate digestion of proteins, carry on limited absorption, and move food (a pasty material called chyme) into the small intestine. Small Intestine
The small intestine is about 1 inch wide and about 12 feet long (in a cadaver, it will measure about twice this length because the muscle wall is relaxed). It is divided into three regions: the duodenum, jejunum, and ileum. Contents pass from the ileum into the large intestine through the ileocecal valve. The small intestine serves as the major site of digestion and absorption in the digestive tract. Most chemical digestion takes place in the duodenum. Large Intestine
The large intestine is about 2.5 inches wide (thus giving it the name “large”) and about 5 feet long. It is divided into four regions:

 Finally the digesta moves to the bottom of the stomach, which is the pyloric region. This region is responsible for secreting mucus to line the digestive membranes to prevent damage from the low pH digesta as it passes to the small intestine. The phloric sphincter regulates the amount of chyme (digesta) that passes into the small intestine. This is an important function not to overload the small intestine with chyme so proper and efficient digestion and absorption of nutrients occurs. In addition, once the chyme leaves the stomach, the material is quite fluid in consistency. Figure 2. Regions of the stomach
Small Intestine, Pancreas and Liver
The small intestine is the major site of nutrient absorption, and is divided into three sections. The first section is the duodenum. The duodenum is approximately 12 inches long and is the portion of the small intestine that ducts from the pancreas and the liver (gall bladder). The pancreas is involved with both exocrine and endocrine excretions.

 The human large intestine is much smaller in length compared to the small intestine but larger in diameter. It has three parts: the cecum, the colon, and the rectum. The cecum joins the ileum to the colon and is the receiving pouch for the waste matter. The colon is home to many bacteria or “intestinal flora” that aid in the digestive processes. The colon has four regions, the ascending colon, the transverse colon, the descending colon and the sigmoid colon. The main functions of the colon are to extract the water and mineral salts from undigested food, and to store waste material.

 The Large Intestine
The large intestine is the terminal part of the alimentary canal. The primary function of this organ is to finish absorption of nutrients and water, synthesize certain vitamins, form feces, and eliminate feces from the body. Structure
The large intestine runs from the appendix to the anus. It frames the small intestine on three sides. Despite its being about one-half as long as the small intestine, it is called large because it is more than twice the diameter of the small intestine, about 3 inches. Subdivisions
The large intestine is subdivided into four main regions: the cecum, the colon, the rectum, and the anus. The ileocecal valve, located at the opening between the ileum and the large intestine, controls the flow of chyme from the small intestine to the large intestine. Cecum
The first part of the large intestine is the cecum, a sac-like structure that is suspended inferior to the ileocecal valve. It is about 6 cm (2.4 in) long, receives the contents of the ileum, and continues the absorption of water and salts.

The small versus large intestine, morphometry and function
Along the length of the human small intestine three regions are recognized, that is, duodenum, jejunum and ileum, while the large intestine encompasses the cecum, the ascending-colon, transversing-colon and descending-colon, the rectum and the anal canal. The terminal ileum region is connected to the large intestine and excessive retrograde flow from the large intestine content into the small intestine is prevented by the ileocecal valve. The mucosa in the intestinal tract is composed of the lumen-exposed monolayer of epithelium that overlays the lamina propria (a layer of connective tissue) and the muscularis mucosae (a thin layer of smooth muscle). The small intestinal villi protrude into the intestinal lumen from proliferative crypts, ensuring the large surface area of the lumen-exposed small intestine mucosa that supports the main function of the small intestine, that is, the absorption of digested food. The immune system of the gut is largely organized in the gut-associated lymphoid tissue (GALT) that plays a major role in the development and maintenance of the immune system. In particular the mucosa (i.e. the lamina propria) of the ileal region of the small intestine is rich in immune cells and encompasses the Peyer's Patches. The barrier function of the mucosa is protected by innate and adaptive immune defences, as well as by the mucus layer that lies on top of the epithelial surface. The mucus layer thickness increases along the length of the small intestine, but remains patchy also in the terminal ileum. Conversely, the colonic mucus layer is a dense and thick continuous layer that is much less penetrable. The large intestine mucosa lacks villus structures and is smooth surfaced and contains proliferative crypts.

The Small and Large Intestines
The word intestine is derived from a Latin root meaning “internal,” and indeed, the two organs together nearly fill the interior of the abdominal cavity. In addition, called the small and large bowel, or colloquially the “guts,” they constitute the greatest mass and length of the alimentary canal and, with the exception of ingestion, perform all digestive system functions. The Small Intestine
Chyme released from the stomach enters the small intestine, which is the primary digestive organ in the body. Not only is this where most digestion occurs, it is also where practically all absorption occurs. The longest part of the alimentary canal, the small intestine is about 3.05 meters (10 feet) long in a living person (but about twice as long in a cadaver due to the loss of muscle tone). Since this makes it about five times longer than the large intestine, you might wonder why it is called “small.” In fact, its name derives from its relatively smaller diameter of only about 2.54 cm (1 in), compared with 7.62 cm (3 in) for the large intestine. As we’ll see shortly, in addition to its length, the folds and projections of the lining of the small intestine work to give it an enormous surface area, which is approximately 200 m 2, more than 100 times the surface area of your skin. This large surface area is necessary for complex processes of digestion and absorption that occur within it. Structure
The coiled tube of the small intestine is subdivided into three regions.

 How do the last 2 regions of the small intestine differ in regards to appearance and function? 1st-duodenum
2nd-jejunum
3rd-ileum
The duodenum is a short "U" shaped tube, approximately 4 inches long (shorter than the jejunum and the ileum). It receives chyme from the stomach and secretions from the liver and pancreas. It also has mucous glands. What is the location and function of the ileocecal valve? The ileocecal valve is located at the junction between the ileum and the cecum. The value limits the rate of food passage into the cecum and helps prevent material from returning into the ileum (small intestine).

Key Points
 The ingested feed exits from the stomach to the duodenum through the pyloric sphincter, which is under hormonal control to not overload the digestive capacity of the small intestine. Small Intestine
The major site of digestion and absorption in monogastric animals is the small intestine. It is composed of three distinct regions: the duodenum, jejunum, and ileum. The duodenum is the point of entry for secretions such as bile from the gall bladder and secretions from the pancreas. A major site of digestion and absorption in monogastric animals is the small intestine. In order to fit into the small body cavity, the small intestine is highly coiled. In addition to the digestive function, the small intestine is also an immune organ and has special features such as gut-associated lymphoid tissue, Peyer’s patches, and Bursa fabricii (in chickens), serving as part of the body’s immune defense. Both digestive and absorptive functions of the small intestine are facilitated by a large surface area. The main increase in surface area is brought about by anatomical features such as villi and microvilli.

 This is not considered a true sphincter because it does at times allow stomach contents to enter the esophagus. Some mammals, like rodents, have a true gastroesophageal sphincter and can not regurgitate (this is why poisoning is an effective measure in killing mice and rats). Stomach
The stomach is a J-shaped pouch that empties its content into the small intestine. It can be divided into three regions: the fundus, body, and pylorus. A pyloric sphincter prohibits backflow from the small intestine into the stomach. The functions of the stomach are to store food as it is mechanically churned with gastric secretions, initiate digestion of proteins, carry on limited absorption, and move food (a pasty material called chyme) into the small intestine. Small Intestine
The small intestine is about 1 inch wide and about 12 feet long (in a cadaver, it will measure about twice this length because the muscle wall is relaxed). It is divided into three regions: the duodenum, jejunum, and ileum.

The small intestine is divided into three regions based on their function, even though they are largely similar from a histological standpoint. The first part of the small intestine is called the duodenum and is the shortest segment. It is curved and surrounds one end of the pancreas. It is separated from the stomach by the pyloric sphincter and receives gastric chyme in small quantities when the sphincter opens. The common bile duct and pancreatic ducts open into the duodenum, where the final stages of digestion occur – both due to pancreatic enzymes and membrane-bound intestinal enzymes. The duodenum also contains glands that produce alkaline secretions that neutralize chyme, along with bile. The second section of the small intestine is called the jejunum and marks the site where absorption of digested nutrients begins. The jejunum contains both villi and microvilli that increase its surface area for absorption. The last segment of th

Stomach
The stomach is a pouch-like organ that lies in the upper left part of the abdominal cavity, just under the diaphragm and next to the liver. Functions
The stomach has five functions: digestion of food
secretion of gastric juices as well as mucus which helps to coat its lining, preventing erosion by gastric juices
secretion of gastric hormones
regulation of the rate at which partially digested food is delivered to the small intestine
absorption of small quantities of water and dissolved substances. It does not absorb very well, except in the case of alcohol. Consumption of alcohol on an empty stomach will quickly increase blood levels. Regions
The major regions of the stomach include: the fundus or the body
the pyloric canal
Structures
The pyloric sphincter (located at the end of the pyloric canal) helps regulate the rate at which gastric contents are delivered to the small intestine. Rugae are thick accordion-like folds within the stomach that allow it to expand during a large meal. This remains permanent when stretched too often during frequent overeating. The stomach has three layers of muscles that lie in three directions:

THE SECTIONS OF THE SMALL INTESTINE
The small intestine is segregated into three basic regions, based entirely on functional and structural bias. The first ten inches from the pyloric sphincter of the stomach is known as the duodenum. It remains in the basic shape of a C, and is considered to be in a fixed position. The duodenum is retroperitoneal, with a small exception of the first few inches in the beginning that draw from the stomach. The inside if the C, the concave side, receives two ducts, one from the pancreas and the other from the liver and gall bladder. These ducts feed the small intestine the necessary bile and pancreatic secretions which help in the digestive process. These two ducts unite to create one single entry point into the small intestine, known as the hepatopancreatic ampulla or the ampulla of Vater. This entry point allows the duct to enter the duodenum and drain the necessary fluids from an elevated point called the duodenal papilla, where bile and pancreatic fluid can then enter the small intestine freely. The sphincter of ampulla, or the sphincter of Oddi, retains the ability to either open or close the duodenal papilla to maintain the appropriate amount of fluids at any given time.

The word intestine is derived from a Latin root meaning “internal,” and indeed, the two organs together nearly fill the interior of the abdominal cavity. In addition, called the small and large bowel, or colloquially the “guts,” they constitute the greatest mass and length of the alimentary canal and, with the exception of ingestion, perform all digestive system functions. The Small Intestine
Chyme released from the stomach enters the small intestine, which is the primary digestive organ in the body. Not only is this where most digestion occurs, it is also where practically all absorption occurs. The longest part of the alimentary canal, the small intestine is about 3.05 meters (10 feet) long in a living person (but about twice as long in a cadaver due to the loss of muscle tone). Since this makes it about five times longer than the large intestine, you might wonder why it is called “small.” In fact, its name derives from its relatively smaller diameter of only about 2.54 cm (1 in), compared with 7.62 cm (3 in) for the large intestine. As we’ll see shortly, in addition to its length, the folds and projections of the lining of the small intestine work to give it an enormous surface area, which is approximately 200 m 2, more than 100 times the surface area of your skin. This large surface area is necessary for complex processes of digestion and absorption that occur within it. Structure
The coiled tube of the small intestine is subdivided into three regions.

 Additionally, it serves as a conduit for a dense branching network of nerves, the submucosal plexus, which functions as described below. The third layer of the alimentary canal is the muscalaris (also called the muscularis externa). The muscularis in the small intestine is made up of a double layer of smooth muscle: an inner circular layer and an outer longitudinal layer. The contractions of these layers promote mechanical digestion, expose more of the food to digestive chemicals, and move the food along the canal. In the most proximal and distal regions of the alimentary canal, including the mouth, pharynx, anterior part of the esophagus, and external anal sphincter, the muscularis is made up of skeletal muscle, which gives you voluntary control over swallowing and defecation. The basic two-layer structure found in the small intestine is modified in the organs proximal and distal to it. The stomach is equipped for its churning function by the addition of a third layer, the oblique muscle. While the colon has two layers like the small intestine, its longitudinal layer is segregated into three narrow parallel bands, the tenia coli, which make it look like a series of pouches rather than a simple tube. The serosa is the portion of the alimentary canal superficial to the muscularis.

Digestion - Lion Nutrition
Digestive system morphology and physiology The low pH of the stomach also serves to cause some hydrolysis of proteins and polysaccharides, and denaturation of proteins, exposing the bonds of the amino acid polymer to further enzymatic digestion in the stomach and small intestine (Cheeke and Dierenfeld, 2010). It also activates the gastric glands to secrete the proenzyme pepsinogen, forming the active proteolytic enzyme pepsin (Cheeke and Dierenfeld, 2010). Ingesta exits the stomach from the pyloric region and enters the duodenum of the small intestine (Cheeke and Dierenfeld, 2010). The release of food from the stomach is controlled by the pyloric sphincter which is regulated horomonally so as not to overload the digestive capacity of the small intestine (Cheeke and Dierenfeld, 2010). The major site of digestion and absorption in autoenzymatic digesters is the small intestine, which is has three distinct regions, the duodenum, the jejunum and the ileum (Cheeke and Dierenfeld, 2010). Both the digestive and absorptive functions of the intestine is facilitated by the large surface area (Cheeke and Dierenfeld, 2010). Digestion is the preparation of ingested nutrients for absorption (Cheeke and Dierenfeld, 2010). Normally only small molecules are absorbed, thus proteins are hydrolysed into smaller units (peptides and amino acids), complex carbohydrates into simple sugars (monosaccharides) and fats into monoacylglycerides and fatty acids (Cheeke and Dierenfeld, 2010). Minerals and vitamins generally do not undergo digestion, and are absorbed as such (Cheeke and Dierenfeld, 2010).

 Additionally, it serves as a conduit for a dense branching network of nerves, the submucosal plexus, which functions as described below. The third layer of the alimentary canal is the muscalaris (also called the muscularis externa). The muscularis in the small intestine is made up of a double layer of smooth muscle: an inner circular layer and an outer longitudinal layer. The contractions of these layers promote mechanical digestion, expose more of the food to digestive chemicals, and move the food along the canal. In the most proximal and distal regions of the alimentary canal, including the mouth, pharynx, anterior part of the esophagus, and external anal sphincter, the muscularis is made up of skeletal muscle, which gives you voluntary control over swallowing and defecation. The basic two-layer structure found in the small intestine is modified in the organs proximal and distal to it. The stomach is equipped for its churning function by the addition of a third layer, the oblique muscle. While the colon has two layers like the small intestine, its longitudinal layer is segregated into three narrow parallel bands, the tenia coli, which make it look like a series of pouches rather than a simple tube. The serosa is the portion of the alimentary canal superficial to the muscularis.

What happens to the Digested Food in the Small Intestine? The small intestine has special cells that help absorb nutrients from the intestinal lining into the bloodstream. It has many physiological features that help in this absorption process. It is a long convoluted tube-like organ, which is around ten feet in length and has a diameter of one inch. There is a thin membrane called the mesentery that surrounds the small intestine and anchors it in place. Many blood vessels, lymphatic vessels, nerves pass through the mesentery. They provide support to the tissues of the small intestine and also help in the transport of nutrients from intestines to the rest of the body. The small intestine is divided into three regions: Duodenum- It is the first section which connects to the pyloric sphincter of the stomach.

Human anatomy systems:
 The superior mesenteric plexus is responsible for innervating the small intestine. Sensory fibers along with postganglionic sympathetic fibers and preganglionic parasympathetic fibers reach the small intestine through these various branches. Branches of the celiac trunk and inferior mesenteric artery along with a direct line from the superior mesenteric artery are responsible for providing the small intestine with ample blood supply. The superior mesenteric vein provides the appropriate venous drainage, which then creates a unified vein with the splenic vein to create the hepatic portal vein. The hepatic portal vein then travels to the liver, where the nutrient laden blood supply can be utilized by the body. SMALL INTESTINE DIAGRAM

The small intestine is segregated into three basic regions, based entirely on functional and structural bias. The first ten inches from the pyloric sphincter of the stomach is known as the duodenum. It remains in the basic shape of a C, and is considered to be in a fixed position. The duodenum is retroperitoneal, with a small exception of the first few inches in the beginning that draw from the stomach.

 In contrast, limited information is available for the human small intestine (SI) microbiota characterized by its relatively low-density (102 –10 7 cells/g), which is largely due to the rapid luminal flow and secretion of bactericidal substances (e.g. bile acids) in this part of the intestinal tract [ 3 ]. The SI is responsible for approximately 90% of the overall energy absorption from the diet [ 4] facilitated by the large surface area of its mucosa. Adequate absorptive capacity depends on maintenance of mucosal integrity that is constantly challenged by its exposure to the luminal milieu, including the microbiota. Mechanisms that contribute to this mucosal integrity, include the production of antimicrobial peptides (AMPs), a physical mucin barrier, and mucosal antibodies. Especially the terminal ileum is associated with the largest mass of lymphoid tissue in the human body, that is, the gut-associated lymphoid tissue (GALT) and Peyer's patches [ 5 ], which are essential for maintenance of a microbiota-accommodating immune homeostasis via dedicated luminal antigen-sampling (see also Box 1 ). Box 1
The small versus large intestine, morphometry and function
Along the length of the human small intestine three regions are recognized, that is, duodenum, jejunum and ileum, while the large intestine encompasses the cecum, the ascending-colon, transversing-colon and descending-colon, the rectum and the anal canal. The terminal ileum region is connected to the large intestine and excessive retrograde flow from the large intestine content into the small intestine is prevented by the ileocecal valve. The mucosa in the intestinal tract is composed of the lumen-exposed monolayer of epithelium that overlays the lamina propria (a layer of connective tissue) and the muscularis mucosae (a thin layer of smooth muscle). The small intestinal villi protrude into the intestinal lumen from proliferative crypts, ensuring the large surface area of the lumen-exposed small intestine mucosa that supports the main function of the small intestine, that is, the absorption of digested food. The immune system of the gut is largely organized in the gut-associated lymphoid tissue (GALT) that plays a major role in the development and maintenance of the immune system.

Digestive System of Snakes The food then passes through the pyloric valve and into the small intestines. The small intestines is a long narrow coiled tube where absorbance of nutrients takes place. The small intestines is divided into three regions: the duodenum, the ileum, and jejunum. The liver, which primarily functions in excreting nitrogenous wastes, storing nutrients, and producing bile, excretes digestive enzymes into the duodenum of the small intestines. Also, the pancreas, which produces insulin and glycogen as well, produces digestive enzymes such as lipases, proteases and carbohydrases and secretes them into the duodenum. At the junction of the small intestines and large intestines is the caecum. The large intestines is the least muscular and most thin-walled structure of the snake digestive system. It passes into the cloacae chamber. This chamber is divided into a copradaeum for receiving feces and a urodaeum for urine and products of the genital organs.

 Small Intestine
Most digestion and absorption of nutrients occur in the small intestine. Because of this, its structure is specially adapted for these functions. Its length alone provides a large surface area for digestion and absorption, and that area is further increased by circular folds, villi, and microvilli. The small intestine begins at the pyloric sphincter of the stomach, coils through the central and inferior part of the abdominal cavity, and eventually opens into the large intestine. It averages 2.5 cm (1 in.) in diameter; its length is about 3 m (10 ft ) in a living person. The small intestine is divided into three regions. The first part of the small intestine is the duodenum, the shortest region, and is retroperitoneal. It starts at
the pyloric sphincter of the stomach and is in the form of a C-shaped tube that extends about 25 cm (10 in.)

The stomach is a bean-shaped organ to the left of the liver, it secretes acids and enzymes that digest food and receives food from the esophagus. Description: The small intestine is divided intro three regions: the duodenum, jejunum, and the ileum. 90% of the digestion and absorption of food occurs here.

 How does the modification relate to the function of the stomach? Allows stomach not only to mix, churn and move food along the tract (circular/longitudinal fiber function) but also to pummel the food, physically breaking it down into smaller fragements and to ram food into the small intenstine (oblique fiber function)
What transition in epithelial exist at the gastroesophageal junction? Squamous cells in the esophagus to columnar cell in the gastric mucosa. How do the epithelia of these two organs relate to their specific function? Simple columnar for gastric is absorption & stratified squamous provides protection in esophagus

 It secretes a large number of enzymes, involved in the digestion of carbohydrates, fats, and proteins. Its proteases are secreted in their inactive form and initially activated through a membrane-bound enzyme in the duodenum called enteropeptidase. A few molecules of an activated enzyme can then create a cascade of active proteases. The pancreas also secretes amylases that digest carbohydrates, and lipases, phospholipases and cholesterol esterases that are involved in fat digestion and metabolism. Hormones secreted by the stomach as well as the intestine control pancreatic secretions. Pancreas Anatomy
Small Intestine
The small intestine is divided into three regions based on their function, even though they are largely similar from a histological standpoint. The first part of the small intestine is called the duodenum and is the shortest segment. It is curved and surrounds one end of the pancreas. It is separated from the stomach by the pyloric sphincter and receives gastric chyme in small quantities when the sphincter opens. The common bile duct and pancreatic ducts open into the duodenum, where the final stages of digestion occur – both due to pancreatic enzymes and membrane-bound intestinal enzymes.

 The ‘small’ term is added because it is shorter in diameter as compared to the large intestine. Where is the Small Intestine located? The small intestine sits in the lower abdominal region. The tubular structure starts from the pylorus sphincter of the stomach. It then coils around itself and leads to the opening of the large intestine, caecum. It covers most part of the middle and the lower section of the abdomen. Small Intestine Location and Anatomy
At the junction point, there is a small pouch-like structure called the vermiform appendix. This is a vestigial organ in human beings and hence it is functionless. Parts of the Small Intestine
The small intestine is divided into three major parts, each characterized by its function and length. The parts of the small intestine are:

Chordata
The Chordate is of the Phylum Chrodata, which taxonomically includes three subphyla: Tunicata,
Cephalochordata, and the Craniata. In this phylum, the common attributes of Chordates include having, for
at least some period of time in their life cycles, an endostyle, a notochord, a hollow dorsal nerve chord,
pharyngeal slits, and a post-anal tail. Some animals in the phylum include Hagfish, sea squirts, fish, and
other marine animals.
The Digestive System of the Chordate
The Digestive System of the Fish
The Digestive System of the Snake (Reptiles)
The Digestive System of the Rabbit
 A small caecum projects from the proximal colon in Boidae. In the snake digestion takes place in its j-shaped stomach, where cells of the stomach secrete digestive enzymes and gastric juices that breakdown proteins. The food then passes through the pyloric valve and into the small intestines. The small intestines is a long narrow coiled tube where absorbance of nutrients takes place. The small intestines is divided into three regions: the duodenum, the ileum, and jejunum. The liver, which primarily functions in excreting nitrogenous wastes, storing nutrients, and producing bile, excretes digestive enzymes into the duodenum of the small intestines. Also, the pancreas, which produces insulin and glycogen as well, produces digestive enzymes such as lipases, proteases and carbohydrases and secretes them into the duodenum. At the junction of the small intestines and large intestines is the caecum. The large intestines is the least muscular and most thin-walled structure of the snake digestive system.

The parietal cells, oxyntic cells or delomorphic cells are cells belonging to the gastric or fundic glands, which are found in the fundus, a region of the stomach of mammals. These are especially important, as they are responsible for the secretion of hydrochloric acid and intrinsic factor. To better understand the functions of cells, it should be noted that the stomach of mammals is divided into four parts or anatomical regions known as cardiac, fundus, Body Y pyloric antrum. The cardia and the pyloric antrum can be seen as the entry and exit points of the stomach, which connect the stomach with the esophagus and the duodenum (first portion of the small intestine) while the fundus and the body represent the largest portion of the stomach. However, according to the type of gland present in each anatomical region of the stomach, some authors assure that it is only subdivided into three histological regions: the cardial region, the fundic region and the pyloric region.

The parietal cells, oxyntic cells or delomorphic cells are cells belonging to the gastric or fundic glands, which are found in the fundus, a region of the stomach of mammals. These are especially important, as they are responsible for the secretion of hydrochloric acid and intrinsic factor. To better understand the functions of cells, it should be noted that the stomach of mammals is divided into four parts or anatomical regions known as cardiac, fundus, Body Y pyloric antrum. The cardia and the pyloric antrum can be seen as the entry and exit points of the stomach, which connect the stomach with the esophagus and the duodenum (first portion of the small intestine) while the fundus and the body represent the largest portion of the stomach. However, according to the type of gland present in each anatomical region of the stomach, some authors assure that it is only subdivided into three histological regions: the cardial region, the fundic region and the pyloric region.

 The muscularis in the small intestine is made up of a double layer of smooth muscle: an inner circular layer and an outer longitudinal layer. The contractions of these layers promote mechanical digestion, expose more of the food to digestive chemicals, and move the food along the canal. In the most proximal and distal regions of the alimentary canal, including the mouth, pharynx, anterior part of the esophagus, and external anal sphincter, the muscularis is made up of skeletal muscle, which gives you voluntary control over swallowing and defecation. The basic two-layer structure found in the small intestine is modified in the organs proximal and distal to it. The stomach is equipped for its churning function by the addition of a third layer, the oblique muscle. While the colon has two layers like the small intestine, its longitudinal layer is segregated into three narrow parallel bands, the tenia coli, which make it look like a series of pouches rather than a simple tube. The serosa is the portion of the alimentary canal superficial to the muscularis. Present only in the region of the alimentary canal within the abdominal cavity, it consists of a layer of visceral peritoneum overlying a layer of loose connective tissue. Instead of serosa, the mouth, pharynx, and esophagus have a dense sheath of collagen fibers called the adventitia.

 The chemical digestion occurs when the acids are excreted from the lining of the stomach to break down the proteins. Small Intestine and Large Intestine What are the three sections of the small intestine and what role does each section play in digestion or absorption? Duodenum is the first section of the small intestine, this is where the first part of digestion is completed. Food is mixed with bile and enzymes both of which help break down the food. Jejunum is where the foods nutrients are absorbed. Lleum is the last part of the small intestine where the bile acids are returned to the liver and any excess water is absorbed. What is the pH within the small intestine and how is this pH maintained? The pH of the region is maintained at 7 or 8 this is the pH that is optimal for the enzymes to function. This is kept at a constant with the bile from the gallbladder. Where do bile and pancreatic enzymes enter the small intestine?

 While the digestive organs and assessor organs are located within the peritoneum, the kidneys, ureters and urinary bladder are located outsider of the peritoneum, and thus, are considered by some scientists to be pelvic organs. Digestive Tract
The organs of the digestive tract consist of the small and large intestines, the stomach, cecum, and the appendix. The stomach is located between the esophagus and the small intestine in the upper left region of the abdomen. The stomach is responsible for the secretion of digestive enzymes and gastric acid required to digest food products. The small intestine is situated between the stomach and large intestine and consists of the three segments (duodenum, jejunum, and ileum), each exhibiting distinct functional properties. The duodenum is situated around the top of the pancreas and receives the digested stomach contents known as gastric chyme. The duodenum functions to neutralize the acid contained in the gastric chyme, as well as break down proteins and fat via enzymes and bile. The jejunum is the middle segment of the small intestine and is responsible for the absorption of sugar, amino acids, and fatty acids into the bloodstream. The final segment of the small intestine is the ileum, which connects to the large intestine. The ileum is responsible for the absorption of vitamin B12, as well as any remaining nutrients.

 Histology of the Large Intestine
Colon biopsy: Micrograph of a colon biopsy. The large intestine, or large bowel, is the last part of the digestive system in vertebrate animals. Its function is to absorb water from the remaining indigestible food matter, and then to pass the useless waste material from the body. The large intestine consists of the cecum, colon, rectum, and anal canal. It starts in the right iliac region of the pelvis, just at or below the right waist, where it is joined to the bottom end of the small intestine. From here it continues up the abdomen, across the width of the abdominal cavity, and then it turns downward, continuing to its endpoint at the anus. The large intestine differs in physical form from the small intestine in being much wider. The longitudinal layer of the muscularis is reduced to three strap-like structures known as the taeniae coli—bands of longitudinal muscle fibers, each about 1/5 in wide. These three bands start at the base of the appendix and extend from the cecum to the rectum.

 Large Intestine Location: The large bowel or colon is that part of the gastrointestinal tract which comes between the small intestine and the anal opening. In other words, it starts from the terminal point of small intestine and ends at the anus. The colon is much wider than the small bowel. And, it is this characteristic which gives it the name of large bowel. Looking like an upside down “U”, it lies in the lower region of the abdomen. Large Intestine Function: It is not just one large intestine function. There are many tasks that the last region of digestive tract has to perform. You can summarize them as follows:

Colon biopsy: Micrograph of a colon biopsy. The large intestine, or large bowel, is the last part of the digestive system in vertebrate animals. Its function is to absorb water from the remaining indigestible food matter, and then to pass the useless waste material from the body. The large intestine consists of the cecum, colon, rectum, and anal canal. It starts in the right iliac region of the pelvis, just at or below the right waist, where it is joined to the bottom end of the small intestine. From here it continues up the abdomen, across the width of the abdominal cavity, and then it turns downward, continuing to its endpoint at the anus. The large intestine differs in physical form from the small intestine in being much wider. The longitudinal layer of the muscularis is reduced to three strap-like structures known as the taeniae coli—bands of longitudinal muscle fibers, each about 1/5 in wide.

Paneth cells are found throughout the small intestine and the appendix at the base of the intestinal glands. The Paneth cell increase in numbers towards the end of the small intestine. Like the other epithelial cell lineages in the small intestine, Paneth cells originate at the stem cell region near the bottom of the gland. However, unlike the other epithelial cell types, Paneth cells migrate downward from the stem cell region and settle just adjacent to it. This close relationship to the stem cell region is thought to suggest that Paneth cells are important in defending the gland stem cells from microbial damage, although their function is not entirely known. Furthermore, among the four aforementioned intestinal cell lineages, the Paneth cells live the longest (18–23 days). Function
Paneth cells secrete antimicrobial peptides and proteins, which are "key mediators of host-microbe interactions, including homeostatic balance with colonizing microbiota and innate immune protection from enteric pathogens." Small intestinal crypts house stem cells that serve to constantly replenish epithelial cells that die and are lost from the villi.

 They propose that further evolution of the technique needs to be subject to a rigorous oversight procedure. Gut organoid
Gut organoids refer to organoids that recapitulate structures of the gastrointestinal tract. The gastrointestinal tract arises from the endoderm, which during development forms a tube that can be divided in three distinct regions, which give rise to, along with other organs, the following sections of the gastrointestinal tract: The Foregut gives rise to the oral cavity and the stomach
The Midgut gives rise to the small intestines and the ascending colon
The Hindgut gives rise to the rectum and the rest of the colon
Organoids have been created for the following structures of the gastrointestinal tract: Intestinal organoid
Intestinal organoids have thus far been among the gut organoids to be generated directly from pluripotent stem cells. One way human pluripotent stem cells can be driven to form intestinal organoids is through first the application of activin A to drive the cells into a mesoendodermal identity, followed by the pharmacological upregulation of Wnt3a and Fgf4 signaling pathways as they have been demonstrated to promote posterior gut fate. Intestinal organoids have also been generated from intestinal stem cells, extracted from adult tissue and cultured in 3D media. Intestinal organoids recapitulate the crypt-villus structure of the intestine, by recapitulating its function, physiology and organization, and maintaining all the cell types found normally in the structure including intestinal stem cells. Thus, intestinal organoids are a valuable model to study intestinal nutrient transport, drug absorption and incretin hormone secretion. Intestinal organoids recapitulate the crypt-Villus structure to high degree of fidelity that they have been successfully transplanted to mouse intestines, and are hence highly regarded as a valuable model for research.

Digestive System of Snakes Digestive System of Snakes
Digestive System of Snakes In snakes, the esophagus is long and can cover up to half the length of the body. The esophagus of snakes has more internal folds than other reptiles, which allows for the swallowing of large, whole prey. Peristaltic movement within the esophagus moves the food downward towards the stomach. The stomach is a j-shaped organ in which most of the digestion occurs in snakes. The cells of the stomach secrete digestive enzymes and gastric juices that breakdown proteins. The food then passes through the pyloric valve and into the small intestines. The small intestines is a long narrow coiled tube where absorbance of nutrients takes place. The small intestines is divided into three regions: the duodenum, the ileum, and jejunum. The liver, which primarily functions in excreting nitrogenous wastes, storing nutrients, and producing bile, excretes digestive enzymes into the duodenum of the small intestines.

 Thus, serotonin acts both in higher regions such as the hippocampus, the amygdala, or the neocortex, as in more internal regions such as the thalamus, hypothalamus, or Nucleus accumbens , And even participates in more primary regions such as the spinal cord or the cerebellum . As is well known, the functions of the upper regions of the brain are very different from those of the innermost structures, so serotonin is expected to play very different roles. The main ones are: 1 - Intestinal function
We will begin by commenting on the functions performed at the physical level. As we have seen before, despite being considered as a neurotransmitter, this substance also carries out activities at the physical level, which is why many people interpret it as a hormone. Leaving aside the nomenclature with which we refer to serotonin, either hormone or neurotransmitter, it has been shown that in the body, the largest amounts of this substance are in the gastrointestinal tract. In fact, the large amount of serotonin localized in the intestines has made it possible to characterize the gastrointestinal serotoninergic system. In this region of the body, 5-HT is responsible for regulating function and bowel movements. It is postulated that this substance plays a major role in the absorption of nutrients, motor activity and the secretion of water and electrolytes. Also, serotonin has been described as an important transducer of intestinal luminal information, so that the stimuli of the intestinal lumen cause its release, which generates vascular, vasodilatory and vascular responses.

In this particular case only the adventitia and tunica muscularis were considered abnormal; therefore a type 1 stricture was considered the most likely diagnosis. Treatment of an Esophageal Stricture in a 1-Month-Old Miniature Shetland Colt
Villus height, crypt depth, epithelial cell height, ratio of villus height to crypt depth, tunica muscularis externa and tunica submucosa were analysed using a linear model including dietary treatment, region of the small intestine, and the interaction between dietary treatment and region as fixed effects, and piglet nested within diet as a random effect. Dietary bovine colostrum increases villus height and decreases small intestine weight in early-weaned pigs

 those found throughout the length of the small intestines and those restricted to one of the three areas. Those found throughout the small intestines include: Tall columnar absorptive cells that reside in the crypts of Lieberkühn and are equipped with microvilli; Mucous secreting goblet cells dispersed between absorptive cells; Undifferentiated stem cells that replace the other cells after they become non-functional or worn; Eosinophillic, lysozyme secreting Paneth cells at the base of the crypts of Lieberkühn that provide antibacterial and phagocytic activity; and
Hormone secreting enteroendocrine cells that regulate the secretion of pancreatic, biliary and gastric juices and activates enteric motility. Goblet cells (histological slide)
Each of the three parts of the small intestines has glands and cells that are exclusively located in that area: The duodenum has light-staining, branched, tubuloacinar Brunner’s glands proximally in its submucosa that secretes its contents as a protective response to the presence of acidic chyme; In the distal ileum, lymphatic aggregates (called Peyer’s patches) covered with phagocytic M-cells, reside in the submucosa and lamina propria of the region;

Those found throughout the small intestines include: Tall columnar absorptive cells that reside in the crypts of Lieberkühn and are equipped with microvilli; Mucous secreting goblet cells dispersed between absorptive cells; Undifferentiated stem cells that replace the other cells after they become non-functional or worn; Eosinophillic, lysozyme secreting Paneth cells at the base of the crypts of Lieberkühn that provide antibacterial and phagocytic activity; and
Hormone secreting enteroendocrine cells that regulate the secretion of pancreatic, biliary and gastric juices and activates enteric motility. Goblet cells (histological slide)
Each of the three parts of the small intestines has glands and cells that are exclusively located in that area: The duodenum has light-staining, branched, tubuloacinar Brunner’s glands proximally in its submucosa that secretes its contents as a protective response to the presence of acidic chyme; In the distal ileum, lymphatic aggregates (called Peyer’s patches) covered with phagocytic M-cells, reside in the submucosa and lamina propria of the region;

Anatomy
Oxygenated blood leaves the heart through the aorta, which descends into the abdominal cavity as the abdominal aorta. The abdominal aorta forms several branches, three of which supply blood to the intestines: the celiac trunk, superior mesenteric artery, and inferior mesenteric artery. Each of these arteries forms many smaller branches that spread throughout the abdomen to specific regions of the intestines. Unlike the other branches of the abdominal aorta, the three arteries that supply the intestines are unpaired arteries and extend from the anterior wall of the aorta. Celiac Trunk
The celiac trunk extends from the abdominal aorta just inferior to the diaphragm and divides into three branches. One of these branches, the hepatic artery, further divides into three more branches to supply blood to the digestive organs. Of these branches, the gastroduodenal artery supplies blood to the pylorus of the stomach and the nearby duodenum of the small intestine.

Water and Cellulose
 A ring muscle that surrounds the anus (anal orifice). After the food has been passed through the small intestine, it enters the large intestine. Within the large intestine, digestion is retained long enough to allow fermentation via gut bacteria that break down some of the substances that remain after processing in the small intestine. Some of the breakdown products are absorbed. In humans, these include most complex saccharides (at most, three disaccharides are digestible by humans). Intestinal Bacteria
The large intestine houses over 700 species of bacteria that perform a variety of functions. The large intestine absorbs some of the products formed by the bacteria that inhabit this region. Undigested polysaccharides (fiber) are metabolized into short-chain fatty acids by bacteria in the large intestine and get absorbed by passive diffusion. The bicarbonate that the large intestine secretes helps to neutralize the increased acidity from the formation of fatty acids. Intestinal bacteria also produce large amounts of vitamins, especially vitamin K and biotin (a B vitamin), which are absorbed into the blood.

Alternative Titles: regional enteritis, regional ileitis
Crohn disease, also called regional enteritis or regional ileitis, chronic inflammation of the digestive tract, usually occurring in the terminal portion of the ileum, the region of the small intestine farthest from the stomach. Crohn disease was first described in 1904 by Polish surgeon Antoni Leśniowski. It was later named for American gastroenterologist Burrill Bernard Crohn, who in 1932, in collaboration with fellow physicians Leon Ginzburg and Gordon D. Oppenheimer, published a thorough description of a then-unknown intestinal disorder they called regional ileitis. Today, Crohn disease is characterized as a type of inflammatory bowel disease (IBD) and has been associated with abnormal function of the immune system and genetic variations. The disease also has been linked to abnormal changes in populations of intestinal bacteria. For example, Faecalibacterium prausnitzii, a normal inhabitant of the human intestinal tract, is found in decreased levels in people with Crohn disease, and Mycobacterium avium paratuberculosis, found in the intestinal tracts of ruminants affected by Johne disease, which is similar to Crohn disease in humans, has been isolated from the blood of some patients. However, despite these associations, the cause of Crohn disease remains unknown. small intestine

 The space constituting the abdomen is termed the abdominal cavity. The borders of the abdominal cavity are comprised of the posterior peritoneal surface, the anterior abdominal wall, the inferior pelvic inlet, and the superior thoracic diaphragm. The abdomen functions to house the digestive system and provides muscles essential for posture, balance, and breathing. Abdomen Anatomy
The abdomen is comprised primarily of the digestive tract and other accessory organs which assist in digestion, the urinary system, spleen, and the abdominal muscles (shown below). The majority of these organs are encased in a protective membrane termed the peritoneum. While the digestive organs and assessor organs are located within the peritoneum, the kidneys, ureters and urinary bladder are located outsider of the peritoneum, and thus, are considered by some scientists to be pelvic organs. Digestive Tract
The organs of the digestive tract consist of the small and large intestines, the stomach, cecum, and the appendix. The stomach is located between the esophagus and the small intestine in the upper left region of the abdomen. The stomach is responsible for the secretion of digestive enzymes and gastric acid required to digest food products. The small intestine is situated between the stomach and large intestine and consists of the three segments (duodenum, jejunum, and ileum), each exhibiting distinct functional properties.

Enzymes speed up reactions by lowering the energy required to activate the reaction How are energy supplying macronutrients broken down into smaller subunits? polysaccharides->disaccharides->monosaccharide The digestion of carbohydrates takes place in the mouth and the small intestine region of the alimentary canal Saliva - secreted by the salivary glands - contains a digestive enzyme called salivary amylase. This enzyme breaks down starch into sugar at pH 6.8 an enzyme that breaks down proteins into smaller peptides (that is, a protease). It is produced in the stomach and is one of the main digestive enzymes in the digestive systems of humans an enzyme that catalyzes the hydrolysis of starch into sugars. Secreted in the saliva, salivary amylase breaks down long-chain and branched carbohydrates, known as amylose and amylopectin, into two- and three-molecule sugars called maltose. an enzyme secreted from the pancreas enters the small intestine through the common bile duct with other digestive enzymes and compounds. Once it enters the duodenum, the first portion of the small intestine, pancreatic amylase converts to its active form. It then functions in the same capacity as salivary amylase on any starches that were not cleaved into maltose molecules in the mouth. The lining of your small intestine secretes three enzymes that aid in hydrolyzing polysaccharides and disaccharides into monosaccharides.

Crohn's Disease
Also called: Regional enteritis, Regional ileitis
Crohn's disease causes inflammation of the digestive system. It is one of a group of diseases called inflammatory bowel disease. Crohn's can affect any area from the mouth to the anus. It often affects the lower part of the small intestine called the ileum. The cause of Crohn's disease is unknown. It may be due to an abnormal reaction by the body's immune system. It also seems to run in some families.

Superficial Collaterals -The collaterals on the superficial areas of the body, where functions of the major meridians manifest themselves. This chart demonstrates the complexity of labeling and understanding the different meridian points. In total, there are over 400 jingmai, the majority of which run along the Twelve Primary Meridians. Because the Twelve Major Meridians are of great importance, it is important to discuss them in greater detail. The Twelve Major Meridians
The Twelve Major Meridians are the primary meridians through which qi flows. They are located in each arm and leg, have yin-yang properties, and are connected to a specific Zang-fu organ. There are six yin meridians that are located in the inner region of the arms, legs, chest, and torso. The six yang meridians are located on the outer region of the arms, legs, head, and torso. A chart of the tweleve major meridians
In total, there are three yin meridians (heart, lung, and pericardium) and three yang meridians (small intestine, large intestine, and sanjiao) of the arm, as well as three yin meridians (liver, kidney, spleen) and three yang meridians (urinary bladder, gall bladder, and stomach) of the leg.

 Phasmids likely function as chemoreceptors. Females may produce pheromones to attract males. Nematodes in general have papillae, setae and amphids, which are the main sense organs. Setae detect motion (mechanoreceptors), while amphids detect chemicals (chemoreceptors). ( Barnes, 1987; Brusca and Brusca, 2003)

Food Habits
Adult E. vermicularis live in the lumen of the transverse and descending colon. Humans are its only host. They feed on blood and tissue cells in the host's intestine. Food boluses move from the worm's mouth to its intestine through the esophagus, which consists of three esophageal regions. These regions create a type of peristalis, forcing the bolus downward.
