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: -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.

Detailed explanation-5: -Mucosal Structure The mucosa projects from the folds into the lumen with finger-like structures called villi approximately 1 mm in length. Villi increase the surface area by an additional 10-fold. The surface of each villus is covered with epithelial cells known as enterocytes.
