What are the most common cells that line the surface of the alveoli and are therefore associated with the exchange of gases within the lungs?

Answer: The epithelial cells

The endothelial cells.

The epithelial cells are pulmonary while the endothelial are vascular

These cells exist as tight-two celled structure for gas exchange in the lungs

They are moistened, thin layered, and use diffuse gradient of oxygen and carbon dioxide to move gases across their wall. s

They are well lined with blood capillaries for rapid absorption of gases into the blood stream,
