Where does oxygen ultimately come from?
When you breathe, you take in oxygen from the air and pass it through your bloodstream. The bloodstream carries the oxygen to your muscle cells, where the mitochondria harvests energy from glucose and organic molecules to generate ATP, which the cells use to contract. Contractions of many cells cause you to move.
Where is oxygen most commonly found?
oxygen is the most common of all chemical elements on earth, being found in water, air, and most mineral and organic substances, including most compounds in the human body. It combines with almost all other elements, and is so reactive that it was given the Greek name ‘oxygen’, meaning acid-forming.

How does the body use oxygen?
How the Body Uses Oxygen. Oxygen is distributed through out most of our body. It is imported from our lungs into our body by the process of diffusion and carried to various organ systems inside red blood cells through binding and unwinding to the respiratory enzyme hemoglobin*, as well as via in our blood plasma.
How does oxygen diffuse into the blood?
Answered 2 years ago. Oxygen diffuses through membranes and into red blood cells after inhalation into the lungs. The heme group (that consists of an iron) of hemoglobin binds oxygen when it is present, changing haemoglobin’s color from bluish red to bright red.
How is hydrogen lost?
It is split, and the hydrogen is either lost or hided. When it is lost, it is to space. Water molecules at high altitude are split by UV light, and the hydrogen is lost, leaving oxygen in the atmosphere. Today that does not produce so much oxygen. Only 3 kg of hydrogen is lost each second.

Where does oxygen come from?
Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen.
How does the body get oxygen?
Secondly, our bodies get oxygen into the cells in the front surface of the cornea by simply absorbing it from the air. Similarly, the outer layers of the skin absorb oxygen directly from the atmosphere. It's true that the skin does not have to be transparent like the cornea, so it can receive oxygen from the blood, which it indeed does.
Which fluid delivers oxygen to the cells in the lens and back side of the cornea?
The aqueous humor itself is the clear fluid that delivers oxygen to the cells in the lens and back side of the cornea. Without red blood cells present to actively clamp on to oxygen molecules and transport them, the aqueous humor must rely on the less-efficient mechanism of simple diffusion to deliver the oxygen.
What color is blood?
However, blood is an opaque red color. If blood flowed directly to the front parts of the eye, we would be blinded. As shown in the diagram at the right, the human eye consists of a round, tough white shell called the sclera which envelops a clear gel-like fluid called the vitreous humor.
Why is blood red?
For the eyes, it is especially important that there be no blood in the front parts. The parts at the front of the eye need to be transparent in order to let light shine into the eye, thus enabling vision. However, blood is an opaque red color.
