Villi significantly increase the rate of diffusion of soluble food molecules in the small intestine through a variety of means: * They are folded to provide a large surface area over which diffusion can take place. They additionally have microvilli to further increase the surface area for diffusion. * They have a large, constant blood supply to maintain a steep concentration gradient. * Their walls are only one cell thick to provide a short diffusion path.
