When your diaphragm pulls down, it is making room for the lungs to expand. The lungs get bigger with air and pushes the diaphragm down. The diaphragm also lowers the internal air pressure. Outside of your body, the air pressure is greater and you suck in air when you inhale. The air then expands your lungs like two balloons being blown up. When your diaphragm relaxes, it moves up and the cavity inside your body gets smaller.
