GENERAL HISTOLOGY

Detailed explanation-1: -Simple columnar epithelium : This type of epithelium is often specialized for absorption and usually has apical cilia or microvilli. These cells line your stomach and intestines.

Detailed explanation-2: -Microvilli are present on the luminal surface of many epithelia, particularly those specialised for absorption. Microvilli increase the area of the free surface of the epithelium available for absorption.

Detailed explanation-3: -Every cell lining the small intestine bristles with thousands of tightly packed microvilli that project into the gut lumen, forming a brush border that absorbs nutrients and protects the body from intestinal bacteria.

Detailed explanation-4: -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-5: -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).
