numbnutz think again about “deoxygenated blood” now remember people breathe out carbon dioxide. so blood on the way out should have twice the oxygen as CO2. get on my level. its common sense

For those who wish to try this, go for it: Prick a finger to make it bleed inside a VACUUM chamber that”s fitted with a glove so the gloved-hand can be stuck inside the chamber, as they do it when working in labs and such, so whatever they are working with or manipulating inside the vacuum chamber is not contaminated with oxygen and other stuff flying around in the air? Maybe that way it can be proven whether blood is really blue or not before it bleeds out and becomes oxygenated in the regular environment? Try it, I’ll wait for your posting with your results. Could be interesting.

this has been such a sigh of relief thank you greg it has been such a huge misconception about red blood turning blue in my class and my teacher is teaching the students that human blood is blue and its been so frustrating beacuse i was the only one trying to explain to them that its a misconception but no one believed me so thank you for this closure

blood appears blue because blue is the only light that isn’t filtered by the skin. It’s an optical illusion much like the illusion of a blue sky or blue oceans.

Search â??Scuba Diving Green Bloodâ? on You Tube for a demonstration of blood colour while diving.
