Surfactant helps to prevent the alveoli from collapsing by .
A) warming the air before it enters
B) humidifying the air before it enters
C) interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar fluid
D) protecting the surface of alveoli from dehydration and other environmental variations

Question

Quizplus · Accepted Answer

Surfactant reduces surface tension in the alveoli by disrupting the cohesive forces between water molecules, preventing alveolar collapse.
