-The pressure changes are brought about by the movement of two set of muscles: internal intercostal muscle and external intercostal muscle.

Because of the above actions occurs, it increase the volume of the thorax, and the pressure in the thorax decreases.

And the atmospheric pressure higher than inside human body effects the gas willing to go in to human body.
-Expiration can explain as when the pressure goes up and made by the pushing of internal intercostal muscles. The volume goes smaller and the gas are pushes out of the body
