We had a discussion at our ESP class. A classmate of mine reported on the Circulatory system. A question was asked whether the color of blood is really red. Some said it is blue.

Blood has to be RED.
When you get a BLOOD TEST or have BLOOD DRAWN, it NEVER hits the oxygen making it turn red! It is RED when it is drawn out of the body.
When it HITS the AIR or OXYGEN then it gets a SMELL.
First thing: Blood is *never* blue. Blood is described as dark red (venous) or bright red (arterial). Our veins look blue because we are looking at them *through* our skin. The blood inside them is dark red and it doesn't reflect light very well. The blood you see when you get hurt is usually venous blood. Arterial blood comes out in spurts. It spurts every time the heart beats. I hope you never see that.
An average adult has about 14 to 18 pints of Blood.
One standard unit or pint of Blood equals about two cups.
There are four main Blood types: A, B, AB and O.
Each Blood type is either Rh positive or negative.
The three main types of cells making up our Blood are the White Blood cells, Red Blood cells and Platelets
Red Blood cells can be stored under normal conditions for up to 42 days.
Frozen red Blood cells can be stored for ten years, and more.
Platelets must be used within five days.

Blood is NEVER blue. Venous blood is dark red, Arterial blood is bright red. Your veins look blue because you're looking at them through the skin, the blood inside them is dark red and doesn't reflect light very well.
So, blood isn't blue, nor does it look blue. Veins, which are whitish in color look blue because they are filled with the darker oxygen depleated venous blood, and the skin difuses the light causing the bluish tint.
It's really surprising how many people still believe that your blood is blue until it comes in contact with air.

The color of blood can depend on several factors, how much oxygen is in, and how fresh it is. It can vary in hue, but is always reddish in tint. Going anywhere from an almost black deep red, garnet or burgandy, to being tinged with blue.

I took anatomy and if i remember right the color of blood in your body is blue and once you cut yourself and oxygen from the outside world hits it, it turns it red.

blue blood is a myth. blood is always red. the reason people think blood is blue is because veins are blue but the blood in them is red.

Blood is never blue or purple! Oxygen saturated blood is darker red and unsaturated blood is lighter red.

It's blue while it's in your body, but the second it touches oxygen, it is red. That is why your veins look blue, not red.

Oxygenated blood is red.
Deoxygenated blood is blue.
It usually appears red in your body, because your lungs and pulmonary arteries are constantly supplying oxygen. Why do you think you need to breath so much?
