Detailed explanation-1: -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.
Detailed explanation-2: -The diaphragm is the most efficient muscle for breathing. It’s a large, dome-shaped muscle located at the base of your lungs. Your abdominal muscles help move the diaphragm and give you more power to empty your lungs.
Detailed explanation-3: -The diaphragm helps in the inspiration and expiration of air in and out of the lungs. At the time of inspiration, the diaphragm contracts, increasing the pulmonary volume, thereby reducing the intrapulmonary pressure to less than the atmospheric pressure, and air moves into the lungs.
