Question
If the partial pressure of oxygen is greater in the alveoli than in the blood, which of the following will occur?
Solution 1
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.
Solution 2
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 higher concentration of oxygen is in the alveoli and the lower concentration is in the blood, so oxygen will move into the blood to try to equalize the concentrations. This process is also facilitated by the thin walls of the alveoli and capillaries, which allow for easy gas exchange.
