Which of the following determines lung compliance?
A) muscles of inspiration
B) alveolar surface tension
C) airway opening
D) flexibility of the thoracic cage

Question

Quizplus · Accepted Answer

Lung compliance is determined by the alveolar surface tension. This is because the surface tension of the fluid lining the alveoli can create a force that resists the expansion of the lungs, making it more difficult to breathe. In healthy lungs, surfactant helps to reduce surface tension and increase compliance.
