Question

Does the number of cell layers or the cell shape play a role in the function of the epithelial tissue? Provide three example.

Answer 1

Yes, the number of cell layers or the cell shape play a role in the function of the epithelial tissue.

There are following three examples:-

1. Simple cuboidal epithelial tissue :- they are found in the lining of the kidney tubules and other ducts and used for secretion and absorption.
2. Stratified cuboidal epithelial tissue :- they are composed of 3-4 layers of cell layers. They are found in lining of sweat gland ducts and used for protection.
3. Pseudostratified epithelial tissue:- found in lining of upper part of respiratory tract and used for secretion and movement.
