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: -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.

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: -Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through. Microvilli: The cells on the villi are packed full of tiny hairlike structures called microvilli.
