When you are dead and you get a cut does your blood still turn red when it hits !


Question:

When you are dead and you get a cut does your blood still turn red when it hits the air?

people have blue blood and the moment the blood and air meet it turns red so people never see there blue blood unless it is there vanes and you can see your vanes through your skin. But when you are dead, if you get a cut or something does your blood not change to red when it hits air? if you do not know the answer to this question, do you know someone who we may be able to ask?


Answers:

it depends on how long the body has been dead, but if the body is still "fresh" then by theory it is yes. All blood is blue until it touches an oxygen molecule...the blue veins carry "old" blood that has been drained of it's oxygen by your body parts, then when the heart pumps out blood it goes by your lungs and collects oxygen molecules by the hemoglobin, and then turns red, it's not the air that makes the blood turn red per say, specifically it's the oxygen.
