Microvilli

Definition

Microvilli are tiny, finger-like projections on the surface of epithelial cells lining the intestines, which increase the surface area for absorption. They play a crucial role in the digestion and absorption of nutrients by expanding the cell's surface exposed to the intestinal lumen.
