Question

what are the functions of villi

Answer 1

Villi are specialised 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

Answer 2

villi (singular-villus) are small finger like outgrowths in the small intestine

villi increase the surface area for absorbtion of food
