HUMAN NUTRITION

Detailed explanation-1: -The individual epithelial cells also have finger-like projections known as microvilli. The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients.

Detailed explanation-2: -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-3: -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-4: -Villi are finger-like projections present in the small intestine, which increases the surface area for absorption of nutrients from food.

Detailed explanation-5: -Listen to pronunciation. (in-TES-tih-nul VIH-ly) Tiny hair-like projections that line the inside of the small intestine. They contain blood vessels and help absorb nutrients.
