Answer:

Explanation:

On inhalation, the diaphragm contracts and flattens and the chest area expands. This contraction creates a vacuum, which draws air into the lungs. On exhalation, the diaphragm relaxes and returns to its shape, and air is forced out of the lungs.

Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
