What's the difference between expiration and expiratory?
Expiration
Definition:
(n.) The act of expiring
(n.) The act or process of breathing out, or forcing air from the lungs through the nose or mouth; as, respiration consists of inspiration and expiration; -- opposed to inspiration.
(n.) Emission of volatile matter; exhalation.
(n.) The last emission of breath; death.
(n.) A coming to a close; cessation; extinction; termination; end.
(n.) That which is expired; matter breathed forth; that which is produced by breathing out, as a sound.

Expiratory
Definition:
(a.) Pertaining to, or employed in, the expiration or emission of air from the lungs; as, the expiratory muscles.
Example Sentences:
(1) Peak Expiratory Flow and Forced Expiratory Mean Flows in the ranges 0-25%, 25-50% and 50-75% of Forced Vital Capacity were significantly reduced in animals exposed to gasoline exhaust fumes, whereas the group exposed to ethanol exhaust fumes did not differ from the control group.
