How is Simple Columnar Epithelium Adapted to its Functions?
The simple columnar epithelium has several adaptations that enhance its functionality:
Microvilli: The presence of microvilli increases the surface area for absorption, which is crucial in the intestines. Tight Junctions: Tight junctions between cells prevent the leakage of digestive enzymes and maintain the integrity of the epithelial barrier. Goblet Cells: These cells provide a protective mucus layer, which is particularly important in the stomach and intestines.
