PATHOLOGY

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 finger-like projections that line the folds (plicae circulares) in the small intestine are called villi. These villi are also full of microscopic hair-like structures called microvilli.

Detailed explanation-3: -Lining the folds of the small intestine are tiny finger-like projections called villi. The villi move nutrients from lumen (opening) of the intestine into the circulatory system.

Detailed explanation-4: -Answer and Explanation: The projections which are present on the surface of some cells are celled Villi. The villi act like finger-like projection on the surface of the cells which are present in some specific types of the cell.
