Quizplus · Accepted Answer

Alveolar ventilation is more important than pulmonary ventilation because it represents the amount of air that actually reaches the alveoli and is available for gas exchange with the blood. Pulmonary ventilation, on the other hand, refers to the total amount of air that is breathed in and out of the lungs, including the air that remains in the airways and does not participate in gas exchange. Therefore, alveolar ventilation is a more accurate indicator of gas exchange efficiency and respiratory function.
