Which of the following determines lung compliance?

Question

Quizplus · Accepted Answer

Lung compliance is determined by the alveolar surface tension, specifically the ability of the alveoli to expand and contract during breathing. This is because the surface tension at the air-liquid interface within the alveoli can create resistance to expansion, which must be overcome during inspiration. The other factors listed (muscles of inspiration, airway opening, and flexibility of the thoracic cage) can affect lung function and breathing mechanics, but do not directly determine lung compliance.
