cold14 Posted May 27, 2005 Share Posted May 27, 2005 when blood is red it is oxygenated, thats why it is moving away from the lungs because it just got a fresh batch of oxygen when it has used up all the oxygen it goes blue and has to go back to the lungs and get a "refill" Link to comment Share on other sites More sharing options...

[M] Posted May 27, 2005 Share Posted May 27, 2005 READ THISIt has a bright red or scarlet colour when it flows from the arteries but a dark red or purple colour when it flows from the veins. AND THISThe pigment haemoglobin contained in these cells is made of protein and iron. It is red in colour, and when it is bound to oxygen as oxy-haemoglobin - it becomes bright red. Red blood cells are replaced continually as they become less efficient after about 120 days. The cells are destroyed by the liver and much of the iron is recycled by the body to make new haemoglobin.

hadiz Posted May 27, 2005 Share Posted May 27, 2005 I've always heard blue until exposed to oxygen, which I always believed to be a myth. So I say red. Link to comment Share on other sites More sharing options...

pto Posted May 28, 2005 Share Posted May 28, 2005 Blood's clear untill it hits O2. Blood cells are red inside your body, they hold the O2 which the fluid blood does not come in contact with. Link to comment Share on other sites More sharing options...
stereopixels Posted May 28, 2005 Share Posted May 28, 2005 Like the rest (79%) of us have said, it's red, whether inside or outside the body. The only reason blood is blue is because when you view it by looking at your veins your skin is breaking down the colour spectrum and so you see it as blue, when in fact it is a dark purpley-red. EDIT: once again I shall back this theory up, where those who have said it is blue have no evidence with which to do so. Please find the myth under the 'human' heading of blood (Wikipedia) http://en.wikipedia.org/wiki/Blood#Humans Link to comment Share on other sites More sharing options...

Liger Posted May 30, 2005 Share Posted May 30, 2005 blood has oxygen in it otherwise your organs are dead and so are you :pinch: . so it is red 585981055[/snapback] when it is deoxigenated it is a very dark red color because of the lack of haemoglobin and O2. This passes through the veins and appears to be blue on the surface of our skin. And no if your mom told u that blood is blue in the veins, she needs to rethink what she said :rolleyes: Link to comment Share on other sites More sharing options...
