HUMAN NUTRITION

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: -Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.

Detailed explanation-3: -Villi are small finger-like projections found in the inner linings of small intestine. These micro structures play a major role in increasing the surface area of the intestine. They contain capillary beds, as well as lymphatic vessels called lacteals.
