OMG! How many people really think you have blue blood?!
Question: Just answered a question someone else asked. She wanted to know if it was true if blood was really blue till it hits the air. I replied in 1st couple sec. that it is always red never blue. 17 other people then answered that it is blue till O2 hits it. One told me to look at my viens. lol 5 others replied it is red always.
So I am just curious how many people really think your blood is at some point blue? Dont be embarrassed if you do I guess many really think it is.
Just to note though your blood is always red. If you are one of the few who think it is blue go to the american medical assciation web site and have a look.
Thanks for all your answers not sure who will get the 10 points. Give me a reson why you should get them I guess. :)

Hemoglobin
A bleeding finger: blood has a distinctive red color.
Hemoglobin is the principal determinant of the color of blood in vertebrates. Each molecule has four heme groups, and their interaction with various molecules alters the exact color. In vertebrates and other hemoglobin-using creatures, arterial blood and capillary blood are bright red as oxygen impacts a strong red color to the heme group. Deoxygenated blood is a darker shade of red with a bluish hue; this is present in veins, and can be seen during blood donation and when venous blood samples are taken. Blood in carbon monoxide poisoning is bright red, because carbon monoxide causes the formation of carboxyhemoglobin. In cyanide poisoning, the body cannot utilize oxygen, so the venous blood remains oxygenated, increasing the redness. While hemoglobin containing blood is never blue, there are several conditions and diseases where the color of the heme groups make the skin appear blue. If the heme is oxidized, methemoglobin, which is more brownish and cannot transport oxygen, is formed. In the rare condition sulfhemoglobinemia, arterial hemoglobin is partially oxygenated, and appears dark-red with a bluish hue (cyanosis), but not quite as blueish as venous blood.
Veins in the skin appear blue for a variety of reasons only weakly dependent on the color of the blood. Light scattering in the skin, and the visual processing of color play roles as well.[16]
Skinks in the genus Prasinohaema have green blood due to a buildup of the waste product biliverdin.[17]
And for Mikey D I hope your dead if you were in a room with no air and cut yourself
yes, the blood appears red because of the oxy-haemoglobin, when we breath in O2 gets into our blood cells and the color becomes red. so even tho u cut urself and measure couple of seconds, the blood always have O2 in it(it must) and look red, unless u touch ur artery which i dont recommend
It's always red...I deserve the 10pts because I am not an idiot.
I don't know for sure but I was always told by an old biddy of an aunt that WE had blue blood!
it is really blue intill it is that website is wrong i cut my self in a room with no air and it was blue so there stfu
Nah, blood is always red. Why would they call red blood cells RED blood cells if it was blue?
My biology teacher last year told us that whole blood being blue thing is a myth.
its red......i should get it because i now its red........
