Pulmonary surfactant works by reducing which property of the alveoli?
ABlood pressure
BOxygen content
CCell division rate
DSurface tension
Answer & Solution
Correct answer: D. Surface tension
1. Surfactant is named for what it does to a surface.
2. A type II alveolar cell secretes pulmonary surfactant.
3. Surfactant is composed of phospholipids and proteins.
4. It reduces the surface tension of the alveoli.
5. Lower surface tension keeps the alveoli from collapsing.
