HUMAN NUTRITION

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: -Microvilli are the finger-like protrusions of the inner wall of the intestine that increase the surface area of the of the intestinal membrane. This increased surface area helps in more absorption of digested food, ions and other nutrients.
