Select the correct statement about the physical factors influencing pulmonary ventilation.
A) Surfactant helps increase alveolar surface tension.
B) A lung that is less elastic will require less muscle action to perform adequate ventilation.
C) A decrease in compliance causes an increase in ventilation.
D) As alveolar surface tension increases, additional muscle action will be required.

Question

Quizplus · Accepted Answer

As alveolar surface tension increases, additional muscle action will be required to overcome the increased resistance to expanding the lungs and increase ventilation. The other options are incorrect: Surfactant decreases, not increases, surface tension; a less elastic lung would require more, not less, muscle action for ventilation; and a decrease in compliance would decrease, not increase, ventilation.
