In the lung,as the partial pressure of oxygen of the blood goes up,the partial pressure of oxygen in the alveolar air goes down proportionally.

Question

Quizplus · Accepted Answer

The partial pressure of oxygen in the blood increases as it absorbs oxygen from the alveolar air, but this does not cause the partial pressure of oxygen in the alveolar air to decrease proportionally. The alveolar air's oxygen partial pressure is primarily determined by the ventilation and the oxygen content of the inhaled air.
