Question
If the partial pressure of oxygen is greater in the alveoli than in the blood, which of the following will occur?
Solution
If the partial pressure of oxygen is greater in the alveoli than in the blood, oxygen will diffuse from the alveoli into the blood. This is due to the principle of diffusion, which states that molecules will move from an area of higher concentration to an area of lower concentration until equilibrium is reached. In this case, the oxygen molecules will move from the alveoli (where there is a higher concentration of oxygen) into the blood (where there is a lower concentration of oxygen). This process is also facilitated by the thin walls of the alveoli, which allow for easy gas exchange.
