THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The lining of the small intestinal mucosa is very highly specialized for maximizing digestion and absorption of nutrients. The lining is highly folded to form microscopic finger-like projections called villi which increase the surface area to help with absorption.

Detailed explanation-2: -Villi are small finger-like projections found in the inner linings of small inestine. These micro structures play a major role in increasing the surface area for absorption of nutrients during the process of digestion.

Detailed explanation-3: -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.
