Describe columnar epithelium in brief ​

Answer 1

$\begin{gathered}{\underline{\underline{\maltese{\Huge{\textsf{\textbf{\pink{Answer: }}}}}}}}\end{gathered}$

• 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

$\large\tt\pink{ \dashrightarrow AnsWer:}$

• The columnar epithelium is composed of epithelial cells that are column-shaped. The cell comprising the columnar epithelium is taller than it is wide. Its height is approximately four times its width. The nucleus in each cell is elongated and often found near the base.

• The columnar epithelium is mainly involved in secretion, excretion, and absorption. The ciliated type can be found in the bronchi, uterine tubes, the uterus, and part of the spinal cord.
• These epithelia are capable of moving mucus or other substances through the beating of their cilia.
