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: -The surface of the small intestine has a finger-like microscale villus structure, which provides a large surface area to realize efficient digestion and absorption.
