when you inhale you get oxygen that that first enters the lungs and then into the left part of the heart.It is driven by your heart into the bloodstream,all the way through the body.The heart pumps blood which transports essential nutrients,oxygen,and other chemicals to every cell in your body.The blood delivers Carbon dioxide into the right portion of the heart,from which it is pump to the lungs.Carbon dioxide leaves your body through the lungs when you exhale.
