Solution
The correct option is A True
Inhalation:
The diaphragm and intercostal muscles (the muscles that link the rib cage) contract during inhalation, causing the lung capacity to expand and the thoracic cavity to enlarge.
Exhaling causes muscles in your chest cavity to shrink and compress your lungs.
As their volume diminishes, the pressure inside the lungs rises.
As a result, air rushes out of the lungs, moving from a high-pressure location to a low-pressure area.
