The quantity of O₂ that will diffuse between the alveolar air and pulmonary blood depends solely on the partial pressure gradients that exist between the alveoli and blood.

Question

Quizplus · Accepted Answer

The diffusion of O₂ also depends on factors like the surface area of the alveoli, the thickness of the alveolar-capillary membrane, and the solubility and molecular weight of the gas, in addition to the partial pressure gradients.
