Answer 2

Step-by-step explanation:

Villi are small finger-like outgrowths present that help in the process of absorption. These are located in the inner walls of the small intestine. Their function is to increase the surface area of the small intestinal wall for absorption of the digested food.

Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.

Although the villi play a role in digestion, they also are essential for the absorption of digested nutrients. ... The villi aid in absorption by increasing the surface area of the intestine and contain specialized cells which transport different types of nutrients into the blood.
