Answer:

To stay inflated, the lungs rely on a vacuum inside the chest. The diaphragm is a sheet of muscle slung underneath the lungs. When we breathe, the diaphragm contracts and relaxes. This change in air pressure means that air is 'sucked' into the lungs on inhalation and 'pushed' out of the lungs on exhalation.Explanation: hope this helps
