Answer :
The partial pressure of oxygen in the alveoli is about 104 mm Hg, while the partial pressure of carbon dioxide in the alveoli is 40 mm Hg.
What is the partial pressure of gases in the alveoli?
The alveoli are tiny air sacs where gaseous exchange takes place between the lung and the bloodstream.
Because oxygen needs to diffuse into the bloodstream while carbon dioxide needs to diffuse out, the partial pressure of oxygen in the alveoli is around 104 mmHg while that of carbon dioxide is 40 mmHg.
With higher partial pressure than in the blood, oxygen from the alveoli will be able to diffuse into the blood. With lower partial pressure than in the blood, carbon dioxide will be able to diffuse from the blood into the alveoli.
