When you breathe in, your diaphragm contracts and is pushed upwards. Your lungs expand and fill with air. The pressure within your chest cavity increases, and the body goes through the gas exchange process, providing red blood cells with oxygen. The carbon dioxide within red blood cells is then transferred into the lungs, and is exhaled along with traces of oxygen and other substances within the air. The diaphragm relaxes, lungs deflate, and pressure within the chest decreases.
