Your heart gives oxygen to blood cells, then those carry oxygen throughout your body, and when they reach your heart again, it refills them with oxygen.
The brain consumes 40% of the oxygen in your blood.

The cornea in the eye does not receive oxygen from blood. Instead, it gets its oxygen directly from the air.
Erythropoietin is produced naturally in the body, mostly by the kidneys. It gives bone marrow the signal to produce red blood cells, which carry oxygen in the blood.

The lungs are responsible for taking in oxygen from the air we breathe and transferring it into the bloodstream. This occurs through the process of gas exchange in the lungs where oxygen moves into the blood vessels in exchange for carbon dioxide.
