Diffusion is needed in the small intestine so that nutrients from digested food can be diffusedinto the blood vessels of the intestine wall. The lining of this wall is called the mucosa and is covere in tiny wrinkles that form indents in the surface. Not only does this increase surafce area but there are tiny hairs called villi as well that add even more surface area. The villi are also covere in microvilli. Rhis means more surface for nutrient absorption. Furthurmore these villi are only one cell thick meaning substances cam easily be exchanged to and from the blood vessels.
