The entire human body relies on oxygen to burn stored energy, turning it into thermal energy sufficient to drive normal human activities. Oxygen is inhaled by the lungs, so the size and number of activities of the lungs are very important; the heart is responsible for sending oxygen through the circulatory system to various organs and parts, so the strength of the heartbeat affects the flow of blood.
