During inhalation, the diaphragm and rib muscles contract → the chest expands → as a result of vacuum, the lungs become inflated. During exhalation, the respiratory muscles relax→ the thoracic cavity shrinks → the air is expelled from the lungs.</li> <li>Keywords: inhalation and exhalation, diaphragm, trachea, bronchi, pleural membranes, lungs.<br/> <br/> </li> </ul> </div> 2020-12-03T11:23:33+02:00
