there arefour points:
1.presence of villi gives large surface area for absorption
2.villi consist of extensive network of blood vessels which allows max assimilation and absorption
3.the length of the small intestine is so long and the digestion is a slow process, thus by the time the food or chyme reaches the end of the small intestine, its completely absorbed
4.intestinal juices present in small intestine speed up the absorption
-> write this in exam and you will pakka get full ;D
the villi in the intestine increases the surface area, which allows for massive absorption
Your small intestine is filled w/ things that look very much like shag carpet. As food travels though there, the "shag carpet" absorbs all the important nutrients.
because the job of the small intestine is to asorb nutrients and stuff
Because its small
Small Intestine.
The small intestine is where the vast majority of digestion and absorption of food takes place.
Majority of digestion occurs in the small intestine.
The digestion is completed in the small intestine.
No, digestion begins in the mouth but also occurs in the stomach and small intestine.
Small intestine
Digestion of some fats can begin in the mouth where lingual lipase breaks down some short chain lipids into diglycerides. However fats are mainly digested in the small intestine. The presence of fat in the small intestine produces hormones that stimulate the release of pancreatic lipase from the pancreas and bile from the liver which helps in the emulsification of fats for absorption fatty acids.
Most chemical digestion occurs in the stomach and absorption occur in the intestines in humans and many other animals.
most digestion occurs in the small intestine where all the nutrients and minerals are extracted and put ino the bloodstream. the stomach just breaks the food down so it can get into the intestine
mouth,stomach and small intestine
The small intestine completes the process of chemical digestion.
Most of digestion occurs in the stomach and most absorption occurs in the small intestine.
