When the volume inside the lungs increases, the intrapulmonary pressure
When the volume inside the lungs increases, the intrapulmonary pressure
Open in App
Solution
The correct option is A decreases
Pressure and volume are inversely proportional to each other.
When the pressure increases, volume decreases, and vice versa. Therefore, when the volume inside the lungs increases, the pressure decreases. At this point, this pressure is lesser than the atmospheric pressure and causes air to gush into the lungs.
