During inhalation, what happens to the diaphragm?

Explanation:
The diaphragm must contract to expand the chest cavity. When it contracts, it moves downward and flattens, increasing the vertical dimension of the thoracic cavity. This expansion lowers the intrapulmonary pressure, allowing air to flow into the lungs. If the diaphragm relaxed and moved upward, the chest volume would decrease, pushing air out rather than drawing it in.
