Answer
Respiration — Respiration is the process of releasing energy by breaking down food (glucose) needed for various activities of the body.

Lungs — The lungs are a pair of pink and spongy, elastic organs located in the chest cavity and help in the exchange of gases. They take in oxygen from the air and remove carbon dioxide from the blood during the process of breathing.

Exhalation — Exhalation is the process of forcing out of the air from the lungs.
