Changes in the alveoli that cause an increase in alveolar surface tension, alveolar collapse, and decreased lung expansion are a result of:
A)decreased alveolar macrophage production.
B)increased compliance.
C)decreased surfactant production.
D)increased stimulation by peripheral chemoreceptors.

Question

Quizplus · Accepted Answer

Surfactant, a lipoprotein produced by type II alveolar cells, has a detergent-like effect that separates the liquid molecules, thereby decreasing alveolar surface tension, increasing alveolar collapse, and decreasing lung expansion.
