What are villi? What is their location and function?
The inner wall of the small intestine has millions of finger-like projections or folds called villi (singular : villus). Each villus has a network of a thin and small blood vessels called capillary close to its surface. These villi give the inner walls of the small intestine a very large surface area. The surface of the villi absorbs the digested food materials and passes them through the blood capillaries.
villis are small finges like outgrowths in the small intestine, the nerves are connected with it, the digestion of food ends in stomach when villi secrets enzymes, and when digestion is completed the veins connectedd to villi takes the energy and transfer it to all parts of the body.
