The lung is a vertebrate invention that allowed the early tetrapods to leave the water and colonize the land. Oxygen is the essential actor in aerobic metabolism and the lung's cardinal function is to mediate the efficient transfer of oxygen from the atmosphere to the circulatory system. Given the lung's essential function, diseases of the lung are often life-threatening or incapacitating.
