The purpose of the lungs are to oxygenate blood. Oxygen is vital for staying alive; so we breathe to bring oxygen into the bloodstream. The purpose of the heart is to pump the blood in a way to oxygenate the body, with the most important area being the brain. It sends the newly oxygenated blood directly to the brain and the rest of the body, and returns the de-oxygenated blood to be re-oxygenated.
