Question

the epithelium that helps in respiratory gas exchange

Answer 1

The epithelium that helps in respiratory gas exchange is stratum corneum

Answer 2

HI MATE....

We can see that gas exchange occurs in the lungs between the air and our blood.

Now, gas exchange in the lungs refers to the movement of oxygen into the blood and carbon dioxide out of the blood.

Oxygen and carbon dioxide move across what we call the respiratory surface, and that consists of an alveolar epithelial cell and a pulmonary capillary endothelial cell.

Now, this respiratory surface is also referred to as the respiratory membrane. Note that the air is on one side of the membrane and blood is on the other side of the membrane.

As you can see from the image above, oxygen moves out of the alveolar air into the blood, while carbon dioxide moves in the opposite direction.

Therefore, we use the term gas exchange, as oxygen is exchanged for carbon dioxide across the respiratory surface.
