Guest Chaos Pudding Posted January 22, 2010 Report Share Posted January 22, 2010 This isn't so much a poll as an experiment, to see how well your biology teachers have taught you. So, what is it? And no fair Wiki-ing it! I want to know what you know or think you know. Link to comment Share on other sites More sharing options...
Skuldur Posted January 22, 2010 Report Share Posted January 22, 2010 I believe that it isn't blue. It's just depicted as blue on drawn pictures. Link to comment Share on other sites More sharing options...
~Wright~ Posted January 22, 2010 Report Share Posted January 22, 2010 Maybe not blue, but I don't think it's red... *looks at veins* Yep, I think it's bluish purplish... The blood that goes through your veins is deoxygenated blood, that goes back to the heart to be oxygenated, and pumped into arteries throughout the body. On your wrist, there are several veins that can be seen, if you look closely. You can see that the veins are a purplish blue color, so yes, deoxygenated blood is blue.

MysticWater Posted January 22, 2010 Report Share Posted January 22, 2010 I wouldn't go as far as blue, but I wouldn't say they are the bright red we think. Maybe a purple-like color. Link to comment Share on other sites More sharing options...

OmegaWave Posted January 22, 2010 Report Share Posted January 22, 2010 Kinda gives it away because your veins are blue if you don't have any cuts....... The oxygen is what give blood it's Red color, a "Chemical Reaction" if you will. So if there's no oxygen being distributed, then yes, it is blue.

It's true that the oxygen makes blood a bright red. But the absence of oxygen doesn't mean that the blood is blue. Hint: What color is blood that has been donated? Note that it's usually taken from veins, and the bags are vacuum sealed. Link to comment Share on other sites More sharing options...

Scatty Posted January 22, 2010 Report Share Posted January 22, 2010 Blood would never be black regardless of oxygen level' date=' Versatility.[/quote'] You fail at organic chemistry. Cells in the blood need oxygen to stay alive, and EVEN the cells in the blood need to actually consume oxygen. No oxygen equals cells dying equals liquid and hydrogen being massively removed from the blood equals carbon equals black. Or have you discovered a way to keep erythrocytes alive without giving them oxygen? That would be indeed the most important thing discovered since the Internet. But, as stated before, even venal blood has oxygen in it. Link to comment Share on other sites More sharing options...

No oxygen equals cells dying equals liquid and hydrogen being massively removed from the blood equals carbon equals black. I disagree. No oxygen = cells dying = liquid and hydrogen being massively removed indeed. In that liquid removed from inside the cell is a large amount of hemoglobin. Massive hemolysis inside a vessel still results in red blood tonality because heme is not decomposed until it reaches the spleen. The only way blood would ever be black was if the cell was much larger than it actually is, especially since it does not contain a nucleus. Seeing as most of its content is hemoglobin, it is impossible for blood to ever be black regardless of how many erythrocytes die (because hemoglobin quantity is much larger than that of any other component in the erythrocyte). If your theory was correct, the spleen would be black, seeing as that's where physiologic hemolysis occurs continuously. Link to comment Share on other sites More sharing options...
Scatty Posted January 22, 2010 Report Share Posted January 22, 2010 You DO realise that hemoglobin contains oxygen anyway, right? And that without that oxygen, the hemoglobin wouldn't be hemoglobin anymore, right? Experiment: kill a mouse, put his blood in a glass, let it there for one week. Where's your God red now?

BehindTheMask Posted January 22, 2010 Report Share Posted January 22, 2010 HEMOGLOBIN is the key to this. Also, the game. Also the floor is lava. Anyway, Hemoglobin gives blood its red colour. Link to comment Share on other sites More sharing options...
