What's the difference between breath and exhalation?

Breath


Definition:

  • (n.) The air inhaled and exhaled in respiration; air which, in the process of respiration, has parted with oxygen and has received carbonic acid, aqueous vapor, warmth, etc.
  • (n.) The act of breathing naturally or freely; the power or capacity to breathe freely; as, I am out of breath.
  • (n.) The power of respiration, and hence, life.
  • (n.) Time to breathe; respite; pause.
  • (n.) A single respiration, or the time of making it; a single act; an instant.
  • (n.) Fig.: That which gives or strengthens life.

Definition:
