Correct Answer is C
Explanation
Choice A rationale:
A pneumothorax, or collapsed lung, occurs when air leaks into the space between the lung and chest wall. This is not directly caused by pressure in the lungs dropping lower than atmospheric pressure.
Choice B rationale:
Bronchioles constricting could lead to respiratory distress, but this is not a direct result of the pressure in the lungs dropping lower than atmospheric pressure.
Choice C rationale:
When the pressure within the lungs drops lower than atmospheric pressure, air flows into the lungs. This is a fundamental principle of respiration.
Choice D rationale:
Air flows out of the lungs when the pressure within the lungs rises above atmospheric pressure, not when it drops.
