the heart does not give the body it's oxygen it is the lungs. The heart is used to pump the blood to the lungs to pick up oxygen and then to pump the blood throughout the body and add oxygen to the blood cells.
Oxygen is used in every cell of the body. It is a reactant in respiration, which gives us the energy to sustain life. Food + oxygen = carbon dioxide + water. This results in the release of energy.
The oxygen goes into your lungs, then into your blood stream. Then carbon dioxide goes into your lungs and thats when you exhale. Oxygen changes to carbondioxide in your body.
