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 are found in areas of the body which are specialized for absorption, such as the digestive tract or kidneys. They function by increasing the surface area of the cell membrane, thus allowing for more materials to be absorbed into the cell at a quicker rate. Unlike cilia, microvilli do not move.
Detailed explanation-3: -Answer and Explanation: The microvilli on epithelium vastly increase the surface area of epithelial cells and thereby allow for greater absorption rates.
Detailed explanation-4: -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.
