Which of the following determines lung compliance?

Question

Quizplus · Accepted Answer

Lung compliance refers to the ability of the lungs to stretch and expand during inhalation. The main factor that determines lung compliance is the surface tension of the alveoli. Surface tension is caused by the attraction between the water molecules lining the alveoli, and it tends to cause the alveoli to collapse. In order to prevent this, surfactant is produced in the lungs to reduce surface tension and maintain the elasticity of the alveoli. Therefore, the correct choice is D, alveolar surface tension.
