1)Villi and micro villi increase the surface area for the absorption of digested food.
2)Epithelial cells lining the intestine have a high volume density of mitochondria, meaning lots of energy for the active uptake of digested food. :)
how is the large artery adpted to its role
Well, the skeletal muscles have adapted in the same way the black guy in X men: first class adapts to his surroundings. Skeletal muscles are mutants. God help us.
The sigmoid colon is found almost at the end of the GIT in the lower abdomen. It is a continuation of the descending colon and becomes the rectum.I.e. oesophagus --> stomach --> duodenum --> jejunum --> ileum --> ascending colon --> transverse colon --> descending colon --> sigmoid colon --> rectum --> anus --> toilet.It is part of large intestine
Villi are finger-like projections in the small intestine. Their role is to help the body absorb nutrients from the food. The villi are little tiny hairs inside the small intestine that absorb nutrients.
The peripheral nerve is the nerve that controls the limbs of the body. The peripheral nerve has adapted to it's role through myelination, where the nerves are tightly compressed and have connections to the spinal cord to control the limbs.
The function of the ileum is mainly to absorb vitamin B12 and bile salts and whatever products of digestion were not absorbed by the jejunum.
The Ileum is responsible for absorption of nutrients into the blood stream. Also the jejunum has the same functionThe Ileum is the last section of the small intestine (its about 12 feet/ 3.6m in length) and joins the large intestine at the ileocecal valve. The role of the small intestine as a whole is its the major digestive system of the body. Digestion is completed in the small intestine and virtually all absorption of nutrients occurs here.the ileum absorbs B12 and bile salts and whatever products of digestion that were not absorbed by the jejumType your a What is the function of the ileum?nswer here... the thing that yeah!
to absorb food
Lacteals
It helps with absorption and mobility
ths is the o
The role of KOH in the experiment IS IT? I DONT KNOW ASK UR TEACHER ....................
The liver has a central role in lipid metabolism. The liver produces bile, which is required for efficient intestinal fat absorption. The post-absorptive stages of metabolism occur from the lipid absorption in the intestines.

The role of the villi in the alimentary canal is to allow for a greater surface area in which the absorption of nutrients can take place.
Small Intestine
The main segments of the human digestive tract are duodenum, jejunum, and ileum. Each of these segments has a specific role that it plays to facilitate digestion.
