Question

why gas is exchange very rapid at alveolar level ?

Answer 1

Answer:

The partial pressure of carbon dioxide in the capillaries is much higher than that in the alveoli. This means that net diffusion occurs into the alveoli from capillaries. The carbon dioxide can then be exhaled as the partial pressure in the alveoli is also higher than the partial pressure in the external environment.

Answer 2

This is due to continuous diffusion of oxygen across the alveolar membrane and the diluting effect of carbon dioxide entering the alveoli to leave the body. Despite this, the partial pressure is still higher in the alveoli than the capillaries, resulting in a net diffusion into the blood.
