Respiration
Definition:
(n.) The act of respiring or breathing again, or catching one's breath.
(n.) Relief from toil or suffering: rest.
(n.) Interval; intermission.
(n.) The act of resping or breathing; the act of taking in and giving out air; the aggregate of those processes bu which oxygen is introduced into the system, and carbon dioxide, or carbonic acid, removed.
