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 correct option is A True. Inhalation: The diaphragm and intercostal muscles (the muscles that link the rib cage) contract during inhalation, causing the lung capacity to expand and the thoracic cavity to enlarge.
Detailed explanation-3: -The processes of inspiration (breathing in) and expiration (breathing out) are vital for providing oxygen to tissues and removing carbon dioxide from the body. Inspiration occurs via active contraction of muscles – such as the diaphragm – whereas expiration tends to be passive, unless it is forced.
