Alveolar surface tension determines lung compliance.

Question

Quizplus · Accepted Answer

Alveolar surface tension plays a crucial role in determining lung compliance. This tension is generated by the type II alveolar cells, which secrete surfactant to reduce surface tension and prevent alveolar collapse during expiration. Without proper surfactant production, the alveolar surface tension increases, making it more difficult for the lungs to expand and leading to decreased lung compliance.
