Mechanism of breathing....
Breathing occurs when the contraction or relaxation of muscles around the lungs changes the total volume of air within the air passages (bronchi, bronchioles) inside the lungs. ... Inspiration occurs when the inspiratory muscles—that is, the diaphragm and the external intercostal muscles—contract.
