Although not among one of the most consciously used body parts, the lung is in play every second, being involved in respiration, arguably one of the most important body actions for survival.

Respiration is responsible for the proper functioning of other body systems, which is seen when the blood is starved of oxygen for too long. A complete shutdown of another system of the body is imminent. In cases of survival, the damage is often done already, especially to the brain. For this reason, the American lung association exists.
