'Blood is blue whilst its in the body and only turns red when it oxidises upon contact with the atmosphere. It's why our veins are blue'
This was from my normally reasonable friend. Jesus, as they say, wept.
Blood is blue when it hasnt been oxidies. Thats what viens carry deoxigenated blood, which is why they're blue.
Arteries carry oxigenated blood, which is why is red.
they reason people bleed red is that when you cut your blood is expossed to oxygen which makes it red...
