GENERAL HISTOLOGY

Detailed explanation-1: -Microvilli are the finger-like protrusions of the inner wall of the intestine that increase the surface area of the of the intestinal membrane. This increased surface area helps in more absorption of digested food, ions and other nutrients.

Detailed explanation-2: -Final answer: Villi increases the surface area for absorption in intestines.

Detailed explanation-3: -SIMPLE COLUMNAR EPITHELIUM: The surface of each villus is covered with simple columnar epithelium . The free surface of these cells has very tiny projections called microvilli, which are specialized for absorption (absorptive cells).

Detailed explanation-4: -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.
