Answer Details
The function of the villi in the alimentary canal is to increase the surface area for absorption. Villi are small, finger-like projections that protrude from the lining of the small intestine. They increase the surface area of the small intestine, allowing for greater absorption of nutrients from digested food. The increased surface area of the villi provides a larger area for the absorption of nutrients such as carbohydrates, proteins, and lipids. The nutrients are then transported to the bloodstream to be used by the body for energy and other functions.
