Which of these conditions applies to alveolar PO₂ at high altitudes

Question

Quizplus · Accepted Answer

At high altitudes, the atmospheric pressure decreases, leading to a decrease in the partial pressure of oxygen (PO₂) in inhaled air. This results in a lower alveolar PO₂ as well, as the diffusion of oxygen from the alveoli to the blood is influenced by the concentration gradient. Therefore, choice B is the correct answer._choices A, C, and D are not applicable to this scenario as they represent different aspects of gas exchange and are not directly related to high altitude conditions.
