What is the function of villi in the small intestine?
Answer and explanation
Correct answer: To increase surface area for absorption
Villi are numerous finger-like projections on the inner lining of the small intestine. Their central role is to greatly increase the surface area available for absorption of digested nutrients. Each villus contains blood capillaries and a lymph vessel, allowing sugars and amino acids to enter blood and many fatty products to enter lymph. Villi do not move food backward, perform breathing or filter blood; therefore, option A is correct.
