Boyle's Law describes the relationship between the pressure (P) and the volume (V) of a gas. The law states that if the volume increases, then the pressure must decrease (or vice versa). ... When the volume of the lungs changes, the pressure of the air in the lungs changes in accordance with Boyle's Law.

We can breathe air in and out of our lungs because of Boyle's law. According to Boyle's law, if a given amount of gas has a constant temperature, increasing its volume decreases its pressure, and vice-versa. ... This decreases their volume, so pressure inside the lungs increases.
