Non oxygenated blood is blue, oxygenated blood is red. So blood in your veins is blue, while blood in your arteries is red. Blood outside the body is red (clearly)

That is wrong im sorry kid but dont beleive everything from your friends or on the internet

Blood is blue because lack of oxygen. When it hits oxygen it goes red.

Neither im just not an idiot

Following a quick google search for a source: http://scienceblogs.com/scientificactivist/2008/04/17/why-are-veins-blue/

Wait, so if I cut one of my veins open, the blood will be blue?

No, because the oxygen in the air will oxygenate the blood and turn it red on contact.
-
Wow, so that process must happen really fast
-
As the blood comes into contact with oxygen it happens, so yes.

Wow, so that process must happen really fast

Plus me, and all my friends are dr.s and we all know that in some veins it's blue, but in others it's red, but as soon as it has 02 in it, it's red.

Ya because you can totaly trust .com sites and not .gov or .org sites

If it was a cited scientific article it would have .org or .gov not untrustworthy .com or .net
