Is it true that blood inside your body before it touches oxygen, is blue

It's really NOT true. And anyway, at what point has blood not come in contact with oxygen?? Even in the uterus, the baby receives oxygen from the mother via the umbilical cord. There's never a time that blood isn't at least somewhat oxygenated.

Yes, your veins appear blue, but I promise you the blood inside them isn't. If this were the case, the blood you see when you have labs done would be blue. It's all venous blood... and it's red. Dark red, given, but definitely not blue.

As much as I love the sarcasm of Abbie's answer, your blood is never blue.

Blood full of oxygen is bright red, and deoxygenated blood (blood lacking oxygen) is dark red. The veins appear blue-gray from outside the body because the tint of the skin. The blood is always some sort of red.

Blood without oxygen is blue. Look at the veins on your wrists(they should be bluish) this blood is moving back toasted your heart and lungs after the oxygen has been dispersed.

It doesn't make sense that your veins are blue because your blood is blue before it is oxidized. Are your veins see-through? I don't think so!

Well, believe it, it's true.

Yes that's why if you look at your veins they are a blueish greenish color
