Mentor, I've really never came across anyone so damn right rude and arrogant in my life. Whether or not you agree with my opinion on this matter or not, I really couldn't care less, but me - and several other members of this forum, as they have posted - believe blood is blue until it comes into contact with oxygen. You seem to have some sort of issue with people disagreeing on stuff with you...

There is no need for you to speak to me in the way in which you have been, and if it continues I assure you, I will be taking this further as I refuse to put up with your simple harrasment and abuse.

At the end of the day, you can post as many links to websites as you want - but that doesn't scientificly prove it's true, nor does showing me 'yourself'. If you disagree with me - fair enough, but a lot of people here do agree with me, so I suggest you start realsing your opinion isn't the only one that matters in this discussion.

Ive come to the conclusion your not worth my time.

Heres your choise.
1. Get back on topic, Provide valid reasoning or evidance for your claim, or a rebuttle for the evidance ive provided.
(attacking my repuation or the reputaion of a website has no effect on the agruments being made)
2. Go bother someone else, theres no point debateing if your not going to debate.

And maybe try and exsplain why there called red blood cells maybe...

That comment is hardly necessary. I have said throughout that it is "my opinion and that is how it remains.
All it is, is that in my opinion the evidence presented here, alongside common sense [the RED blood cell notion] makes it clear that my own opinion, and Gomme's and Mentor's are correct.

Sorry, that seemed a bit to global, it wasn't actually meant to include you as I do value your opinion.

Obnoxious was the perhaps the wrong word to choose. I was simply implying to his opiniated attitude towards me and other members, not willing to listen to anyone elses point of view.

It seems the old misconception that blood is blue when it is deoxygenated will never die.

Human blood is red, ranging from bright red when oxygenated to dark red when not. It owes its colour to hemoglobin, a metalloprotein compound containing iron in the form of heme, to which oxygen binds. There exists a popular misconception that deoxygenated blood is blue and that blood only becomes red when it comes into contact with oxygen. Blood is never blue, but veins appear blue because light is diffused by skin. Moreover, the blood inside is dark red and exhibits poor light reflection. From a physiological perspective, veins and arteries appear similar when skin is removed and are seen directly.

Ostinato (Assistant Forum Manager) Please do not post pointlessly.

Aye i've always thought it was red.

Never knew people could get so wound up over what colour blood is!! :p

I never knew people were so pathetic as to BAN people for being right, just becuse there to big headed and childish to admit when there wrong.. suppose thats what happens when you have prepubsent kids on the admin team *cough* ostinato *cough*

Wayne. (Forum Administrator) Please stay on topic and don't insult staff members. Oh, and by the way, he didn't ban you.

i guess the only way to settle this would be to go in a deoxygenated tank and cut yourself :P
you'd probably die if you wasnt quick enough but the argument would be settled :D

ps for the record my opinion is that blood is never blue. theres no/not enough oxygen in the blood test tube to deoxygenize all the blood that comes out, so the colour it goes into the tube is the colour its gotta be in your body :p

I thought it was blue/green when unoxygenated.
