When you breathe in or inhale, the diaphragm muscle contracts. Inhaling moves the diaphragm down and expands the chest cavity. Simultaneously, the ribs move up and increase the size of the chest cavity. There will be no space and less air pressure inside the lungs. The air pushes from the outside where there is higher air pressure.It pushes into lungs where their is lower air pressure. When you breathe out or exhale, the diaphragm muscle relaxes.The diaphragm and ribs return to their original place. The chest cavity return to its original size. There is no less space and greater air pressure inside the lungs. It pushes the air outside where there is lower air pressure.
