The correct description of the role of the diaphragm during inhalation is:
The diaphragm flattens, making the chest cavity larger, and air flows in.
During inhalation, the diaphragm contracts and flattens, which increases the volume of the thoracic cavity and lowers the pressure inside, causing air to flow into the lungs.
