Best Answer

Oxygen diffuses across cell membranes into cells, where it is taken into the mitochondria and used as a hydrogen acceptor during the production of ATP to produce water.

Oxygen begins its journey in the human body when we breathe. It passes into the lungs (along with all the other gases in the air) and diffuses across the alveoli of the lungs and into the red blood cells where it binds to hemoglobin. Four oxygen molecules will bind to each hemoglobin molecule. From there, it is pumped throughout the body and performs its life-giving function. Without oxygen, we would not exist.

Why is oxygen important to your human body?

Oxygen is important cells as without oxygen the human body is unable to release enough energy to support life. In theory any other element in the oxygen-group on the Periodic Table can be used to release energy but because other elements in that group are not easily turned into gases they can't used. Last comment; Oxygen is not important for blood; its important for the blood cells themselves and other cells. Blood and blood cells are very different.
