Question:

Given below a diagram of a section of an alveolus with a pulmonary capillary. Which of the following is a correct statement for diffusion of gases?

Options:

1. Diffusion of O₂ and CO₂ from A to B or B to A takes place with the same rate.
2. O₂ will diffuse faster from A to B than CO₂ from B to A
3. Only O₂ will diffuse from A to B not CO₂ from B to A
4. Only CO₂ will diffuse from B to A, not O₂ from A to B

Solution:

O₂ will diffuse faster from A to B than CO₂ from B to A due to the difference in partial pressures.
