Question

Describe columnar epithelium in brief
​

Answer 1

Explanation:

Simple columnar epithelia are tissues made of a single layer of long epithelial cells that are often seen in regions where absorption and secretion are important features. The cells of this epithelium are arranged in a neat row with the nuclei at the same level, near the basal end.

Answer 2

The columnar (meaning 'pillar-like') epithelium facilitates movement across the epithelial barrier. It is present where absorption and secretion occur, as in the inner lining of the intestine, tall epithelial cells are present.
