" The oxygen which gives life to your body is absorbed into your blood through the delicate membrane of your lungs.
Besides that, carbon-dioxide is exchanged with the environment.
But while the lungs absorb the oxygen, they are not responsible for the movement which makes the inbreath possible.The lungs themselves contain no muscles.
Some of the breathing movement comes from small muscles around the lungs, located in between the ribs, and from certain muscles in the shoulders and upper back. However, the main force behind the breathing comes from the diaphragm- a dome-shaped structure just below the lungs, and above the abdominal organs, attached at the inside of the ribcage.
The diaphragm functions like a piston in a cylinder. When contracting and moving down it creates a vacuum in the lungs, thus creating the inbreath.
When it relaxes, it returns to its dome-like shape, pushing air out of the lungs as you breath out.
This simple cycle of contraction and relaxation of the diaphragm is what creates full and natural breathing."
