The most important function of villi in the small intestine is

• A. To provide strength to the intestine
• B. To provide space for capillaries and lacteals
• C. To provide increased surface area for absorption of digested food
• D. To provide habitat for bacteria

Answer 1

The correct option is C To provide increased surface area for absorption of digested food

Villi are tiny, finger-like projections from the wall of the small intestine. They line the inner surface of the small intestine. Their role is to increase the surface area within the small intestine. This will lead to the increase of the surface area of absorption as it is the main function of the small intestine.
