Answer Details
The function of the villi in the alimentary canal is to increase the surface area for absorption. The villi are tiny finger-like projections that line the small intestine. They increase the surface area available for absorption of nutrients, such as carbohydrates, proteins, and fats, by up to 600 times. The villi are covered with microvilli, which further increase the surface area. This allows for more efficient absorption of nutrients into the bloodstream, which is then transported to the rest of the body for energy and growth.
