<P> 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 . They have a rich blood supply to keep a concentration gradient . </P>
