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

some of it is, the blue blood is just the blood without oxygen and is in your veins, your arteries carry red blood cells with oxygen.

No, the "blue blood turns red when it is exposed to air myth is false"

No. The vein is so blood looks blue. air has nothing to do with it. When you get your blood tested the blood inside the tube is red and the tube is air-free. The blue blood thing is just misconception.

Kind of. It all has to do with oxygen in the blood. Your arterial blood is red because it has oxygen in it. The lungs oxygenate your blood, it goes through the heart and into the arteries and gets delivered through the arterial system to the body. The veins bring the unoxygenated blood back to the lungs. Look at your hands and see how the veins are blue. That is because it is not oxygenated. As soon as oxygen hits blood it turns red. So, even though blood is drawn by a lab from a vein, as soon as it exits your body it hits oxygen, and that is why the blood in the tube is red. (Found this on the internet) (I think it's a myth)

I heard that it is a myth and that it is really clear, but looking at it threw the skin creates an illusion making it look blue.

Veins are blue, that's why it looks blue through your skin. Unoxygenized blood is blue, whereas oxygenized blood is red.

It's blue until oxygen hits it, then it turns red.

Some is and some isn't. Blue blood is blood that has no oxygen, and red blood has oxygen.

All blood, no matter the source, is some shade of red. Oxygenated blood is the brightest red and venous blood (deoxygenated blood) will be the darkest shade of red. Blue blood is only a myth. I honestly don't know why people continue to believe the myth with the wealth of information available at their fingertips. ( no offense) As a matter of fact there is even a marginal amount of oxygen in venous blood.. Some people with congenital problems have a mixture of both oxygenated and deoxygenated. I could go on, but I think you get the point. Cheers

NO!!! Blue blood is NOT REAL. It is maroon if it isn't oxygenated though. Take it from a nurse (ME!)
