GENERAL HISTOLOGY

Detailed explanation-1: -Microvilli increase the surface area of the small intestine which helps in absorption.

Detailed explanation-2: -Answer and Explanation: The three structural adaptations of the small intestine that increase its surface area are its the circular folds or plicae circulares, the villi, and the microvilli.

Detailed explanation-3: -Villi are tiny, fingerlike projections on the lining of the small intestines. As they protrude out, they increase the surface area in with digested nutrients can be absorbed. Larger surface area means more material can be absorbed and at a faster rate, as more of the lining is exposed to the material to absorb it.

Detailed explanation-4: -Villi are tiny, finger-like projections from the wall of the small intestine. They line the inner surface of the small intestine. Their role is to increase the surface area within the small intestine. This will lead to the increase of the surface area of absorption as it is the main function of the small intestine.

Detailed explanation-5: -The inner surface of the mucosa has many finger-like projections called villi. The villi increase the surface area of the small intestine, which helps it absorb digested food.
