A tissue through which gases are exchanged between the blood and the air in the lungs.
a) stratified squamous epithelium
b) simple squamous epithelium
c) simple culumnar epithelium
d) simple cuboidal epithelium

Answers

Answer:

B- simple squamous epithelium.

Explanation:

Alveoli consists of simple squamous epithelium which is the main site for gas exchange. Thus, the correct option is B.

Gas exchange through the process of pulmonary respiration takes place in the alveoli (singular alveolus) of the lungs.

Alveolus is made up of two types of cells - type I and type II alveolar cells.

Type I alveolar cells are simple squamous epithelial cells supported by a thin elastic basement membrane. These cells form a continuous lining of the alveolar membrane and are the main sites for gas exchange.

Type II alveolar cells are septal cells that are present in between the type I cells. They secrete a fluid to keep the surface between the cells moist and it also contain surfactants for reducing the surface tension and preventing the collapse of alveolus.
