ASurface tracking
BSurface tension
CSurface texture
DSurface transfer
Answer & Solution
Correct answer: B. Surface tension
1. Wet alveoli would tend to collapse shut.
2. Surfactant counteracts that tendency.
3. Type II alveolar cells secrete pulmonary surfactant, which reduces the surface tension of the alveoli.
4. So the answer is surface tension.
