The duodenum is the upper portion of the small intestines in mammals. The duodenum is the section of the intestines that connects to the stomach and pancreas.It's the location where digestion takes place.he duodenum's function is to accept chyme from the stomach and complete the digestion of food. Chyme is the mixture of stomach acid and swallowed food. Bile released from the gallbladder is also delivered to the duodenum for fat digestion.
The small intestine is the major site for digestion and absorption of nutrients. The small intestine is up to 6 meters long and is 2-3 centimeters wide. The upper part, the duodenum, is the most active in digestion.Secretions from the liver and pancreas are used for digestion in the duodenum. Epithelial cells of the duodenum secrete a watery mucus. The pancreas secretes digestive enzymes and stomach acid-neutralizing bicarbonate.alivary glands secrete salivary amylase, an enzyme that begins the breakdown of starch into glucose. Mucus moistens food and lubricates the esophagus. Bicarbonate ions in saliva neutralize the acids in foods. Swallowing moves food from the mouth through the pharynx into the esophagus and then to the stomach.
