Atmospheric pressure is the force per unit area exerted against a surface by the weight of the air above that surface in the atmosphere of Earth. In the context of the respiratory system, it plays a crucial role in breathing mechanics as it influences air movement into and out of the lungs.
The act of expelling air out of the lungs, influenced by changes in lung volume and atmospheric pressure.
