When you inhale oxygen enters your body and oxygenates blood then oxygenated blood is distributed to every part of the body. Then blood goes to capillary where the exchange of gas happens. Blood then gets de-oxygenated and carries carbon dioxide to the heart then the lungs and goes out of your body through exhaling.
