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: -Absorption in the Small Intestine As shown in Figure below, the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries.

Detailed explanation-3: -Finger-like structure is one of the typical membrane structures, as shown in Fig. 1. It is also called macrovoid structure.

Detailed explanation-4: -Millions of microscopic, finger-like projections called villi (VIH-lie) line the inside of the small intestine. The villi make lots of surface area for nutrients to get absorbed into the blood. Then blood brings the nutrients to the rest of the body.

Detailed explanation-5: -Villi are small finger-like projections found in the inner linings of small inestine. These micro structures play a major role in increasing the surface area for absorption of nutrients during the process of digestion.
