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.
How do your lungs work? The contraction and relaxation of your diaphragm controls the movement of your lungs. When the diaphragm contracts, it becomes flatter, the pressure in the chest cavity is reduced and the lungs expand resulting in rushing of air into them.
Chest muscles move upwards and outwards. The diaphragm (a muscle under the lungs) moves down. This makes more space for the lungs which fill up with air from the mouth and nose.
