Explanation:
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: -The columnar epithelium of the stomach contains the mucus-secreting cells and in the microvilli, it is highly absorptive as it increases the absorptive surface area.
