No. I thought that too, but that means there is no oxygen in your body.. Thus, you'd be dead.

No it isn't cause there is oxygen in ur blood so that disentangle make any sense

The blood of a human being is supposed to be red. However, the quality of the red factor differs depending on the specific person. Some people have a blood that is slightly darker than the normal red color.

The color of your blood in your body is actually blue until it hits oxygen, then it turns red

Yeah it is blood is always red unless you happen to be an icefish then it is clear. It looks blue because of the way your eyes perceive light. The viens and arteries you have are white they arent even blue.

well once it leaves the body then technically it hits oxygen so it turns red

What about this? When you donate blood it is dark red, if the blood is exposed to oxygen then it is no good and can't be used. So why is it dark red?

Vein color is determined in large part by the color of venous blood, which is usually dark red (and not blue as is commonly believed) as a result of its low oxygen content. Veins appear blue because the subcutaneous fat absorbs low-frequency light, permitting only the highly energetic blue wavelengths to penetrate through to the dark vein and reflect off. A recent study found the color of blood vessels is determined by the following factors: the scattering and absorption characteristics of skin at different wavelengths, the oxygenation state of blood, which affects its absorption properties, the diameter and the depth of the vessels, and the visual perception process.[2]

This is what my cousin who is an internal medicine doctor said. "Vein blood is blue, artery blood is red." But I don't understand that because the blood that is in the veins also go through the arteries. But that's what he said.
Report as
So I guess it's both red and blue while still in the body.
Report as
But I looked it up on mayo clinic and webmd and they both say that blood is always red. I'm wondering if my cousin is wrong.
Report as
@Feller: can you post a site proving the blood is blue?

That site is just a blog... Not reliable at all. And it doesn't even say that blood is blue. If you read the whole thing then you will see that.

Wrong. Blood is never blue. Ever. Period. (And, this is an excellent example of why you should never ingest information from Yahoo Answers uncritically.) The bright red color of arterial blood stems from a complex that's formed between hemoglobin, iron, and molecular oxygen. This complex mainly absorbs higher energy (shorter wavelength) blue and green light, leaving behind primarily just red wavelengths for our eyes to detect. However, even when blood is largely depleted of oxygen, it is never blue: it's more of a deep maroon color. And, although I have not participated in a surgery myself, those who have (including my girlfriend, a veterinary student) assure me that in surgery, veins within the body do not appear blue either. So, not only is blood not blue, veins on their own aren't either. "Blue veins", then, are a phenomenon unique to the skin.

Deoxygenated blood looks blue because you're seeing it through your skin."A vein looks blue because red light travels far enough into the skin to be absorbed by the blood in the vein. If the blood vessel is far enough below the skin, however, blue light--which would normally also be absorbed by the vein--reflects out of the skin before reaching the vein. So the light reflecting from tissue over the vein contains less red light than blue, giving the vein a bluish cast." (Mayo)
In the face of a discrepant event, people still claim blood is blue. Consider the following: Blood taken for medical exams is extracted through venous circulation and collected in a vacuum tube - yet the blood collected is not blue!

In medical pictures of the human body they always make artery blood red and venous blood blue, they just do that to differentiate between the veins and the arteries.

Blood is always red. You know when doctors take your blood from the tube...there is no air in that tube. And we were just talking about this the other day too. Your veins are blue but not your blood. True facts.

The Vein Is A Blood Vessel That Carries Blood From The Capillaries Toward The Heart And Are Visibly Blue. The Blood Inside Of These Vessels Are Contained Red. The Only Red Visible Internal Stream Is The Artery. Therefore, Blood Is Red. Although It Is Not Externally. When The The Skin Is Cut, The Reason Why Our Blood Is Red Is Because A Very Small Piece (Varied) Is Cut Open Therefore The Blood Leaks.

Your blood is red inside and out. If you have ever had an IV injection, it is proof that your blood is red in your veins when it flashes back into the syringe of clear liquid.

I'm actually getting pissed about all these people acting like they know something just because they heard it from someone else. Blood doesn't turn blue when it hits oxygen... The purpose of blood is to transport oxygen!!! When O2 goes from the alveoli in the lungs into the pulmonary veins it is now bright red because it's oxygenated. After delivering the O2 to whichever tissues or organs via the systemic arterial circulation it becomes a darker red and heads back to the right side of the heart via the venous system and back to the lungs for more OXYGEN!! It's an amazing process that keeps on going until the end of our life.

Good answer. You know, I actually asked a doctor about it and he said "Vein blood is blue, artery blood is red." He happens to be my cousin, I was sure that he was going to say that it's always red. I guess he believes that myth also.
Report as
HaHa!! Really?! Man I sure don't claim to know it all but this is one I'm almost positive about. Maybe he's just thinking of all the charts showing the circulatory system where the veins are blue....
I'm going to write another comment for these people to consider.
Report as
I can't put a 2nd answer.
If a person was cut, and the wound is spurting arterial blood at the same pace as the beating of the heart, do they really think the blood would change from blue to red in an instant?
Also, we all have red blood cells. Nobody has blue blood cells.
LoL ok I'm done talking about this!

Good grief, blue?... Arterial (oxygenated) blood is bright red, venous (oxygen depleted) blood is a darker shade of red. There are a few medical conditions that could change the colour of blood such as poisoning with certain metals, but for all intents and purposes, your blood is red.
