The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. In air-breathing vertebrates like human beings, respiration takes place in the respiratory organs called lungs.
The most common examples of respiration occur in two places: in human lungs as part of breathing and in cells through a process called cellular respiration. Humans breathe to oxygenate their blood, and cells breathe to acquire oxygen to be able to break down glucose for the energy that they need.
