Question

what is the function of the columnar and suqmous epithelium.​

Answer 1

Answer:

Simple epithelium

Function and classes Function: absorption and filtration processes Classes: squamous, cuboidal, columnar, pseudostratified

Pseudostratified columnar Location: trachea and most of the upper respiratory tract (ciliated cells) Function: secretes mucus which is moved with cilia

Answer 2

COLUMNAR EPITHELIUM:

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.

SUQMOUS EPITHELIUM:

The suqmous epithelium of epithelia lines the inner surface of all blood vessels (endothelium), forms the wall of alveolar sacs in the lung and lines the body cavities (mesothelium). The primary function of simple squamous epithelia is to facilitate diffusion of gases and small molecules.
