your body needs red blood cells to survive, red blood cells have a particular job, they Carry oxygen through your bloodstream to all your muscles and flesh. your muscles and flesh need oxygen to work properly (this is why when you cross your legs, sometimes your legs feel funny) they also make your blood look red, which doesn't help you at all, but wouldn't you look weird if whenever you got a cut you bled clear? :)
