the right side of the heart receives blood and pumps to the lungs while the left side receives blood from the lungs and pumps it to the rest of the body

When you breathe, the blood pumped from your heart picks up oxygen from your lungs and carries it to the different parts of your body that require the oxygen to function properly.
