The type of epithelial tissue that is present in the walls of capillaries and lung alveolar sacs to allow the easy diffusion of oxygen and carbon dioxide is called:
|
|
simple cuboidal epithelium
|
|
|
simple squamous epithelium
|
|
|
simple transitional epithelium
|
|
|
simple columnar epithelium
|
Explanation:
Detailed explanation-1: -The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.
Detailed explanation-2: -Answer and Explanation: Simple squamous epithelium is the cell type that is best suited for gas diffusion in the alveoli. Gases like oxygen (O2) and carbon dioxide (CO2) must easily pass through the alveolar membrane and the endothelial membrane.
Detailed explanation-3: -The alveolar ducts and alveoli consist primarily of simple squamous epithelium, which permits rapid diffusion of oxygen and carbon dioxide.
