The blood starts from the heart where it gets pumped out to all the body, the oxygen in the blood gets absorbed by the body parts and the carbon dioxide gets released in the blood. Then the blood returns to the heart where it gets pumped to the lungs and the oxygen enters the blood when we inhale and the deposited carbon dioxide gets released into the atmosphere when we exhale. The newly oxygenated blood goes back to the heart where the process gets repeated.
