Detailed explanation-1: -In exhalation, the diaphragm moves upward and the chest wall muscles relax, causing the chest cavity to get smaller and push air out of respiratory system through the nose or mouth. Every few seconds, with each inhalation, air fills a large portion of the millions of alveoli.
Detailed explanation-2: -Muscles and bones help move the air you inhale into and out of your lungs. Some of the bones and muscles in the respiratory system include your: Diaphragm: Muscle that helps your lungs pull in air and push it out. Ribs: Bones that surround and protect your lungs and heart.
Detailed explanation-3: -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-4: -Respiratory muscles are skeletal muscles whose function is to pump air in and out of the lungs.
Detailed explanation-5: -Action: diaphragm is the main inspiratory muscle, during inspiration it contracts and moves in an inferior direction that increases the vertical diameter of the thoracic cavity and produces lung expansion, in turn, the air is drawn in.
