Boyle has a few laws. The one I was refering to basically says air will want to go from high pressure to low. If air pressure inside the lungs is higher than outside the body, air will naturally want to flow out untill there is equal pressure both inside and outside the body. After that point, to get air outside the body, muscular contraction is required.
