Scientific definitions for inhalation

inhalation
[ ĭn′hə-lāshən ]

The act of taking in breath. Inhalation results from the negative pressure in the lungs caused by contraction of the diaphragm, which causes it to move downwards and to expand the chest cavity. The resulting flow of air into the lungs restores a pressure equal to that of the atmosphere. Also called inspiration Compare exhalation.
