The main reason we use oxygen is in the process of cellular respiration. In order for our bodies to change the energy in glucose to the energy of ATP which is ready for our cells to use, we have to pass electrons down an electron transport chain. Oxygen is the final acceptor of those electrons as well as of the H+ (hydrogen ions). Oxygen plus the electrons and hydrogen ions makes water molecules. Without oxygen to accept these electrons, the whole process will stop. The waist product of this is co2 or carbon dioxide. the body gets rid of this by exhaling

oxygen enables the cells of the body to release the energy stored as high-energy chemical bonds in our food, and enables them to use that energy to do what cells do: namely, to keep us alive, heart beating, brain thinking, and kidneys turning our Diet Cokes into unplanned pit stops. Virtually every cell in the body needs oxygen in order to perform its part in the complex symphony of skills and judgement.
