Excercise Can Create Oxygen Debt



All the cells in your body need oxygen for respiration and all of this oxygen is supplied by the lungs. The oxygen is carried by the blood to every part of the body.
Sometimes, cells may need a lot of oxygen very quickly. Imagine you are running in a race. The muscle in your legs are using up a lot of energy. To produce this energy, the mitochondria in the muscle will be combining oxygen with glucose as fast as they can, the energy for the muscle.
