Respiration \Res`pi*ra"tion\ (r?s`p?*r?"sh?n), n. [L.
respiratio: cf. F. respiration. See {Respire}.]
1. The act of respiring or breathing again, or catching one's
breath.

2. Relief from toil or suffering: rest. [Obs.]

Till the day
Appear of respiration to the just
And vengeance to the wicked. --Milton.

3. Interval; intermission. [Obs.] --Bp. Hall.

4. (Physiol.) 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.

Note: Respiration in the higher animals is divided into:
({a}) Internal respiration, or the interchange of
oxygen and carbonic acid between the cells of the body
and the bathing them, which in one sense is a process
of nutrition. ({b}) External respiration, or the
gaseous interchange taking place in the special
respiratory organs, the lungs. This constitutes
respiration proper. --Gamgee.
※ In the respiration of plants oxygen is
likewise absorbed and carbonic acid exhaled, but in the
light this process is obscured by another process which
goes on with more vigor, in which the plant inhales and
absorbs carbonic acid and exhales free oxygen.
