ANATOMY

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: -These villi are also full of microscopic hair-like structures called microvilli. Villi and microvilli help increase the surface area of the small intestine which supports optimum absorption of nutrients from the digested food.

Detailed explanation-3: -Villi are finger-like projections present in the small intestine, which increases the surface area for absorption of nutrients from food.

Detailed explanation-4: -The digestive and absorption capacities of the small intestine are greatly enhanced by circular folds and fingerlike projections of the intestinal mucosa called microvilli.
