subtle. nicely done. :)

The earth has magnetic poles, and if we didn't have iron in our blood, we wouldn't stick to the Earth and we'd fall off and die. [/notserious]

our body uses Iron to move Oxygen through our bodies. ( I saw that ninja turtles t-shirt, haha )

Our red blood cells use the iron to bind up oxygen to carry it around to our cells. this is why depleted blood cells look blue! We basically have rust in our veins. As a side note, Vulcans have green blood because their blood uses copper to bind the oxygen in the same way, so it turns green when oxidizes like the statue of liberty!

I like your view in that first link. You have my respect, Sir Psudonym. Way to put things into perspective.

Because we could create swords from our fallen enemies in battle

There is something strange about that picture. Not the braces or location... I know there is no baby Question Duck or even an egg.

Seeing a talking egg would be pretty surreal though. More surreal than a talking duck.

Because our red bloodcells' cores have the iron to transport the oxygen...

...I think.

When the iron we eat is absorbed by our small intestine, it binds to and is transported by the protein transferrin to make it to the bone marrow where it'll create "heme". The end product would be 4 heme groups, and that'll merge with a globin portion (a four polypeptide chain), which creates "hemoglobin", which due to iron can bind reversibly to O2. It could also combine with CO2, H+, CO and NO, but the focus is usually on the O2.

*goes back to studying*

It is a component of the protein hemoglobin which can carry either 80 or 60 (I can't remember which...) times more oxygen than the same volume of water

What is in your blood?

I used to work for a company by the name of HEMOSOL so those who know of what they speak got the basics pretty much right. Mind you there is a lot more to the chemistry that Wikipedia or most other online publications barely scratch.

Now as to why Iron and not say, Copper like a Trilobite, or Magnesium or some other metal? That is a good question not so easily answered.

I have a picture like that, but I'm wearing a Jurassic Park shirt.

I think the observation deck was closed that way, but pressing my face up against those giant windows I wondered if I could see so far I would see the very building I was in. Not physically possible, but you get the point.

Ishtar (Guest), Jul 02, 2014, 08 am

Others have answered this question well, however I believe the reason it is Iron is because it has more bonding power than copper and is more plentiful than magnesium.

Also red blood cells are always red, it's only when seen through skin and the blood vessel walls that blood looks blue. When seperated plasma is almost clear, white blood cells are white and red blood cells are red, de-oxygenated or not.

I once heard that giant squid have copper-based blood, and it's blue! It also only works up to 8 degrees C. The blue makes sense if you remember what copper sulfate looks like; it's *very* blue!
