The diaphragm is a muscle that moves or pushes up your lung when you exhale and down when you inhale in order to allow more space for oxygen to fill your lung. Also, your chest expands as you breath in and relax as you exhale.

allows your ribs to move up and down when you breath the intercostal muscles contract.these pull the ribcage upwards.so the chest increases in volume when we breath out the intercostal muscles relax which lowers the ribcage.the chest decreases in volume see the diagram below for help The intercostal muscles are located between the ribs and they lift the diaphragm allowing oxygen to flow in and out of the lungs. Basically, they aid in breathing.
