Editing Boyle's law (section)

==Human breathing system==

Boyle's law is often used as part of an explanation on how the [[breathing]] system works in the human body. This commonly involves explaining how the lung volume may be increased or decreased and thereby cause a relatively lower or higher air pressure within them (in keeping with Boyle's law). This forms a pressure difference between the air inside the lungs and the environmental air pressure, which in turn precipitates either inhalation or exhalation as air moves from high to low pressure.<ref>Gerald J.
