Oxygen

Oxygen is a chemical compound. It is very related to its molecule, (varies) H2O,(equation H2O) and is VERY important to multi-celled organisms, so that is a huge milestone.
How the human body reacts/Respiration System
The human body works like MANY boxes. One of them is breathing, which works for LITERALLY Life. So, be sure to thank it, I’m not judging. The human body accepts molecules who have 2 oxygen atoms, because actually Ozone is very dangerous, with 3 oxygen atoms. Oxygen is carried by red blood cells, to capillaries, who take oxygen and release carbon dioxide, so your body is healthy.
