• It is blue...

    Until it is oxidized. Obviously. It's the same principle with rust or any other chemical reaction where color changes. Now, if you will excuse me, I have a Slaanesh Patrol party to attend.

  • Blood is blue inside your body

    Blood may be red when you bleed from a mild cut or scrape. However it only turns that way when it is oxidized. While inside your body your blood is blue. One of my teachers even told me that. You may not be able to see your blood inside your body,but take my word for it,it is blue inside your body.

  • Blood Is Not Blue.

    If blood turns red when it hits oxegen then it has to be red when it's in your body because there is oxegen in your body. How else would you breathe? People just think it's blue because your vain a are blue. Also, if you bleed in an ocean what color is it? Excactly.

  • No it's not.

    This is a myth that everyone believes, but it's not true at all. People only believe that because they're veins are blue. Blood is always red even when it's deoxygenated. Here's a bit proof, when a doctor needs to give you needle to draw blood from you he/she uses a vacutainer so they can place in a test tube, and there's no oxygen in the tube or the vacutainer .


  • Blood is never blue unless you have an unhealthy increase of copper in your circulatory system

    The myth that blood is blue stems for the belief that your blood is blue because your veins look blue. Its just an optical illusion because the skin scatters the blue in light to form a blue vein. And if blood only turns red when air hits it, How is your blood being blue when air is being constantly put through veins with the circulatory system hmmmm.

  • It is RED

    Contrary to what many people think, the blood in our veins, i.E., deoxygenated blood, is not blue. In fact, no kind of human blood is blue. If anything, deoxygenated blood is even redder than regular, oxygenated blood. If you have ever had your blood drawn and noticed its color, you would clearly know that deoxygenated blood is a dark red.Octopuses and horseshoe crabs have blue blood. This is because the protein transporting oxygen in their blood, hemocyanin, is actually blue.The blood of a vulcan is green, according to the story anyway, and this is presumably because the stuff that carries oxygen in the vulcan's blood is green.But our blood is red. It's bright red when the arteries carry it in its oxygen-rich state You can double check this the next time you are at a doctor's office and need to have a blood sample taken. If you are brave enough to look at the blood being drawn, it is notable dark red, it is the blood from your veins that is low in oxygen.Throughout the body. And it's still red, but darker now, when it rushes home to the heart through the veins.

  • Only in Medical Atlases

    The blue/red color scheme is only true in medical textbooks. They do it so that it's easier to identify what's what. Cadavers are injected with colored latex to displace the coagulated blood and make learning exercises easier as well.

    Blood is either bright crimson (oxygenated) or a kind of dull rust (deoxygenated). I should know, I helped move a couple dozen cadavers for a bunch of neurosurgeons.

  • Blood is never blue

    The color of blood is red due to the large number of red blood cells. Blood is both red inside and outside of your body, NOT blue when it is inside of your body. People claim, "It is blue until oxidized" but hell no it's not haha. It is just an illusion given off by our skin, making blood vessels appear blue.

  • Put is simply no.

    The opposing side's argument is that because our blood is not oxidized it is blue, this is false. One of the main functions of our blood cells is to carry oxygen throughout the body meaning that if our blood were not oxidized we'd be dead. We think our blood is blue because our veins our blue but this is just an outdated myth and nothing more.
