The ability of your heart and lungs to work during prolonged exercise

Cardiorespiratory endurance is the ability of your heart and lungs to work during prolonged exercise. The heart is responsible for sending oxygenated blood to the rest of the organs of the body. If the heart is unable to do that, the body collapses.
