Bleeding on Mars

[tnilC]

Unoxygenated blood is red
Red Blood is Blue
Blue blood is from veins
Red blood is from arteries
Blood is always red before it is blue then red again, depending on a vein or artery.
Oxygenated blood is red.

No, at the worst, it'd be dark red.

Blood is never blue, it just looks that way through the skin.

yeh i thought blood being blue was an urban legend...

no, your veins are blue because the blood has no oxygen. if you cut a vein it bleeds red cause its hitting the oxygen. unoxygenated blood is blue.

No, it's not, trust me, I've drawn gallons of venous & arterial blood, once it isn't visualized through the skin, it's a dark red.

And I've drawn it into a syringe sans O2, so it didn't turn red after being exposed to air.

I don't doubt that blood is always red, but I doubt that the vacuous state in a syringe is devoid of O2.

That's it. There's nothing else left to do. One of you is going up there and trying it.

It's okay, if they don't, we'll just drive a rover over to their body.

And I an sure the rock grinder can be used creatively. 😀

Test it in Doom 3. Play one of those outside parts with enemies and get hit a lot, maybe you can see some blood.

The hemoglobin still has 02 molecules on it even after they've hit the capillary level & transferred off some of the molecules to the tissues.

Trust me, I've seen sh1tloads of blood in bypass machines, arterial lines, venous lines, dialysis machines, plasmaphoresis machines, etc, where the blood has no contact with athospheric O2.

Actually the difference in color between arterial & venous blood is very small, it's just slightly darker. In severely hypoxic patients the blood is very dark red, but never blue.
