Answer 1

Answer:

The first phase is called inspiration, or inhaling. When the lungs inhale, the diaphragm contracts and pulls downward. ... When the lungs exhale, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases. As a result, the lungs contract and air is forced out.
