Study Notes

Gas Diffusion in the Lungs

Oxygen diffuses from the alveoli into the blood due to a pressure difference, as the partial pressure of oxygen in the alveoli is higher than in the blood.
Alveolar pressure is a measure of the partial pressure of gases within the alveoli, specifically the pressure of oxygen and carbon dioxide.
Carbon dioxide diffuses from the blood into the alveoli due to a pressure difference, as the partial pressure of carbon dioxide in the blood is higher than in the alveoli.
