Question

Quizplus · Accepted Answer

Surfactant is a fluid produced by type II alveolar cells within the alveoli. It reduces surface tension and prevents the alveoli from collapsing during exhalation, thereby allowing them to inflate during inhalation. Tissue fluid, plasma, and serous fluid are not involved in the inflation of alveoli.
