GENERAL HISTOLOGY

Detailed explanation-1: -Microvilli on the surface of epithelial cells such as those lining the intestine increase the cell’s surface area and thus facilitate the absorption of ingested food and water molecules.

Detailed explanation-2: -Microvilli, found in tightly packed arrays on the apical surfaces of polarized epithelial cells, increase the surface area of the cell exposed to the lumen to enhance absorption and secretion.

Detailed explanation-3: -Microvilli can be found on the exposed surface of the epithelial cells of the small intestine and of the proximal convoluted tubule of the kidney. Microvilli should not be confused with the intestinal villi, which are fingerlike projections at the epithelial lining of the intestinal wall.
