GENERAL HISTOLOGY

Detailed explanation-1: -The finger-like projections found on the surface of the small intestine is known as villi. Villi increases the surface area of the small intestine to absorb the nutrients. Each villus is approximately 0.5-1.6 mm in length. Villi also help the intestines to move food along the digestive pathways.

Detailed explanation-2: -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: 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.
