Want this question answered?
i dont know but i think that the villi absorbs the energy or food substance by the small holes.
Absorption of digested food.
The villi is found in the inner wall of the small intestine , it is covered with many finger like folds( Villi). The villi absorbs more digested food and is absorbed to the bloodstream.
If you mean the hairs on the cells they are villi and micro-villi
more the blood supply ,the more will be the absorption of digested food.
Plicae and villi
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. :)
A tiny projection that absorbs digested food in the small intestine is called the villi.
Villi are largely present in the lower digestive tract. Their function is not only to absorb the digested foodstuffs but also they greatly increase the surface area for absorption.
these are in the ileum wall in the small intestine and they are rsponsible for absorption of nutrients into the bloodstream
More than 50% must be removed before there is a significant reduction in capability Duodenum and jejunum can perform each other's roles in digestion and absorption
Different types of nutrients are absorbed through small finger like structures called Villi.
