How Do Body Cells Receive Oxygen?
All cells in the body receive oxygen through the red blood cells. The blood is carried to the lungs where the red blood cells take on oxygen, it then returns to the heart and is pumped by the heart out to the body through your veins, and eventually to the tiny capillaries, where the oxygen is distributed to the body and all organs. The capillaries then pick up de-oxygenated red blood cells and returns them through the arteries back to the heart then the lungs to be re-oxygenated again.
