Q. Brush border epithelium occurs in:
Solution:
Columnar epithelium is characterised by the presence of tall pillar-like cells, which resemble polygonal columns. The oval nucleus is generally present at the base of the cell. The function of columnar epithelium is secretion or absorption, and it is found in the inner surface of the intestine, stomach, gall bladder, endometrium, etc.
The small intestine is lined by simple columnar epithelium, whose free ends are thrown into finger-like projections, i.e., microvilli. It increases the surface area for efficient absorption, and it is often referred to as brush-border.
