GENERAL HISTOLOGY

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 surface of the small intestine has a finger-like microscale villus structure, which provides a large surface area to realize efficient digestion and absorption.

Detailed explanation-3: -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-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: -On the surface of each columnar cell there are about 600 very fine projections called microvilli that further increase the absorptive area of each villus.
