Select the correct statement about the physical factors influencing pulmonary ventilation.

Question

Quizplus · Accepted Answer

As alveolar surface tension increases, additional muscle action will be required. This is because surface tension creates a tendency for alveoli to collapse, so more muscle action is required to inflate them. The other statements are incorrect; a more elastic lung would require less muscle action, surfactant helps decrease surface tension, and a decrease in compliance would decrease ventilation.
