Dick Montage Posted April 30, 2005 Share Posted April 30, 2005 When blood has oxygen in, it's red. When it doesn't it's blue. Hence blood going fromt he heart in veins is red, but coming back in arteries is blue. This is why we are pink, etc. But look at your wrist, you can see the blue arteries.

pepsihabbit Posted April 30, 2005 Author Share Posted April 30, 2005 Your *blood* does not ever *look* blue. The blue things you see under your skin are veins. Veins are really whitish in color but because the blood is dark and the skin difuses the light, the veins *look* blue. Link to comment Share on other sites More sharing options...

Dick Montage Posted April 30, 2005 Share Posted April 30, 2005 OK, but my point is valid. I got my GCSE and left the science there! Pepsi, if you are going to contradict me so strongly, why even bother asking the question then? I was taught that it was blue when no oxugen. Hence our lips turn blue, etc!

Bawx Posted April 30, 2005 Share Posted April 30, 2005 People think blood it blue until it touches air. False. The blue you see in your vein. Blood is pretty much always a shade of red. Right? Link to comment Share on other sites More sharing options...

Angel Blue01 Posted April 30, 2005 Share Posted April 30, 2005 Blood is colorless. The red bloodcells give it color. I thought it was purple, not blue. Link to comment Share on other sites More sharing options...
Bazildondude Posted April 30, 2005 Share Posted April 30, 2005 Blood is always red. This is due to the oxygen pickup molecule haemoglobin pigment being red. Haem is always present in a blood cell, and will always be red. The blue of the vein is 'just because', that's beyond my scope. But yes, blood is always red, NEVER blue.

gdodson Posted April 30, 2005 Share Posted April 30, 2005 Plasma is colorless, red blood cells are obviously red and I don't know about the color of platelets. Link to comment Share on other sites More sharing options...
_I am Reptar Posted April 30, 2005 Share Posted April 30, 2005 Well when doctors see red blood cells isn't that enought to say it's red? Or they'd be blue blood cells. Link to comment Share on other sites More sharing options...
leedogg Posted April 30, 2005 Share Posted April 30, 2005 Human blood is red, ranging from bright red when oxygenated to dark red when not. It owes its colour to hemoglobin, a metalloprotein compound containing iron in the form of heme, to which oxygen binds. There exists a popular misconception that deoxygenated blood is blue and that blood only becomes red when it comes into contact with oxygen. Blood is never blue, but veins appear blue because light is diffused by skin. Moreover, the blood inside is dark red and exhibits poor light reflection. From a physiological perspective, veins and arteries appear similar when skin is removed and are seen directly. http://en.wikipedia.org/wiki/Blood#Anatomy_of_blood Link to comment Share on other sites More sharing options...
Barney T. Administrators Posted April 30, 2005 Administrators Share Posted April 30, 2005 Sorry.... I can give you the definative answer here...... Blood rich in oxygen (arterial blood) is bright red. Blood that is oxygen poor (venous blood), is dark maroon in color. The elastic walls of the blood vessels make the blood look blue, but it is not. When you give blood for lab tests or to give it as a donor, it comes from your vein and is very dark. The tube that it is drawn up in has no oxygen....... it is simply a vacuum tube.
