Answer Details
The villi in the small intestine are finger-like projections that line the inner surface of the intestine. Their significant function is to increase the surface area for absorption of nutrients from digested food into the bloodstream. This absorption is made possible by the presence of microvilli on the surface of the villi. The microvilli create a brush border, which greatly increases the surface area available for the absorption of nutrients such as glucose and amino acids. The villi also contain blood vessels and lacteals that help in the transport of absorbed nutrients to the liver and the rest of the body.
