Question

Imagine a medication that would completely eliminate surface tension in the lungs. Compliance of the lungs would become:

larger than normal

same as normal

less than normal

Answer 1

Ans : large than normal

when the surface tension from lungs completely eliminate that condition alveoli act as small bubbles.A thin layer of alveolar fluid coats luminal surface of alveoli and exerts a force known as surface tension.

surface tension eliminated lungs have high compliance.

high compliance elastic fibre easily stretched reduce surface tension
