Diaphragm during inspiration:

Correct! Wrong!

The diaphragm is a large, dome-shaped muscle of respiration located below the lungs. During inhalation or inspiration, the diaphragm contracts and flattens, and the chest cavity expands. This contraction creates a vacuum, that pulls air into the lungs. During exhalation, the diaphragm relaxes and the thoracic cavity gets smaller, and the air is forced out of the lungs.
