If the villi of the small intestine are reduced, which function will be affected the most?
Answer and explanation
Correct answer: Absorption of digested food
Villi increase the inner surface area of the small intestine and bring absorbed nutrients close to blood capillaries and lymph vessels. If their number or size is reduced, the available area for absorption falls, so fewer digested nutrients enter the circulation. Option A is therefore correct. Chewing occurs in the mouth, air entry belongs to respiration, and clotting is a blood-protection process.
