Detailed explanation-1: -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-2: -The diaphragm is the main muscle used for breathing. The muscles between your ribs: Called intercostal muscles, these muscles play a role in breathing during physical activity. Abdominal muscles: You use these muscles to help you breathe out when you are breathing fast, such as during physical activity.
Detailed explanation-3: -The muscles of respiration are the muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing.
Detailed explanation-4: -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.
