But just because you have a gym membership that you actually use doesnât mean you canât also have a few things at home for doing other types of workouts that you donât have time for at the gym, or for those days that you just canât make it out the front door.
The inside wall of the small intestine needs to be thin, with a really big surface area. This allows absorption to happen quickly and efficiently. If the small intestine had a thick wall and a small surface area, a lot of digested food might pass out of the body before it had a chance to be absorbed.
The small intestine is an important organ for digestion and absorption of nutrients. In this lesson you will learn about the enterogastric reflex. You will also learn how intestinal movements, such as peristalsis, segmentation, and pendular movement, improve digestion and absorption.eristalsis moves food along the small intestine, but we also see two other movements within the organ. While these two movements do not push the food along the tract like peristalsis, they do mix the chyme with the digestive juices and bring particles of food into contact with the wall where they can be absorbed.
