Answer:
The mechanism of breathing involves two main processes: inspiration and expiration. Inspiration occurs when the diaphragm and the external intercostal muscles contract. ... The contraction or relaxation of muscles around the lungs changes the entire volume of air inside the lungs, and so does the pressure.
