Rust is a chemical reaction between metallic iron and oxygen. The human body has iron in it existing as iron oxide complexes, but not as pure metallic iron.

Iron In The Human Body

Because the iron in the body is already in the "rusted" Fe^+2 form. It is not in neutral, metallic, elemental, form of Fe^0 as what you're ordinary iron nail is when you see it rusting.
The iron in the human body has already reacted with oxygen as a metal complex in the heme of the red blood cell.

iron rusts because iron is present in its primitive, ie, pure form outside..
But in the human body, the iron is in complex ion with other materials..
On a funny note..
it doesn't have enough TIME to rust.. because its caled here and there..

Well we only have a little iron in our bodies so you wont see rust flaking off someone like a neglected car left in the back yard for ten years.
In another sence we do rust. Blood gets its bright red color from something called hemogloben which is comrprised mostly of iron. so once it is introduced to the oxygyn from your lungs it more or less rusts and turns your blood bright red.
On the nastier side of things, feces is colored by rust in a way. Feces by nature is not brown but is a yellowish color. When blood cells die the bodiy deposits it in your intestinal tract. The remaining hemoglobin then stain the feces the familiar brown color.
So in a way we do rust.

The iron carrying components of the human body
( red blood cells ) do oxidize / rust / absorb oxygen..

Hi ,
our blood contains about 3-4 grams of iron and is distributed throughout the body in hemoglobin, tissues, muscles, bone marrow, blood proteins, enzymes, ferritin, hemosiderin, and transport in plasma. The greatest portion of iron in humans is in hemoglobin , so if if the blood exposes to the environment it oxidizes and turns dark brown color.

Hi,
you are talking about oxidation. If I was made of iron your question would be valid.
Fact is we do use oxygen it helps us grow using the compounds within our body that are available.
Oxygen combines with alot of other elements, one is hydrogen, which produces water.

Since we're not composed of mostly metal, I really don't know.
