Question
If surfactant is deficient in lungs, what happens-
| A. |
Surface tension decreases, compliances increases |
| B. |
Surface tension increases, compliance decreases |
| C. |
Both surface tension & compliance increases |
| D. |
Both surface tension & compliance decreases |
Show Answer

Correct Answer � B Explanation |
 |
Surfactant decreases surface tension and hence increase in lung compliance. Therefore a deficiency of surfactant will cause increase in surface tension and decrease in lung compliance.
It permits lungs to be more easily inflated and increases compliance
