Blood isn't blue,if it is,then why do we have RED blood cells.
-
Blood that contains hemoglobin (such as in humans and other vertebrates) is always red. The reason veins appear to be blue is due to the lack of oxygen. If you hold your hand up to a light source, your hand will glow red because of the blood being red.

Some dude at my school said blood was blue. He said it changes red once it hits oxygen. I just asked,"How does it change so quickly?"
I should tell him what you said tomarrow. XD -

As Ting said, itz blue without oxygen.

No it's the chemicals in the covering of the vein that's why the vein looks blue on your wrist
