Answer 2

hey, UR right.. it's red AND blue..same damned blood/stuff.. It's red coming out of your heart as it's oxygenated and all that.. lungs pump 'er in, the heart sticks the oxygen in the blood (damned if I know why it's red..) What's makin the blood blue is the crap it's picking up from roaming around all those miles of arteries in your body.. it's the impurities coming back.. yeah, go into a couple of ventricles in the heart and voila! I'll be damned if it doesn't turn red .. hell of a thing, is it not?!? later

Answer 3

It is actually blue and red in your body. The oxygenated blood, after passing through lungs, is red. The deoxygenated blood is blue. It's red outside your body because it comes in contact with oxygen.

Answer 4

its only blue when it is deoxygenated. So, blood coming from the heart is red; to the heart is blue.
when deoxygenated blood leaves the body it comes into contact with oxygen and turns red again.

Answer 5

Your blood is red when it is oxygenated; it is red when it leaves the heart/lungs. It is blue when the oxygen has been depleted from it. When your blood is exposed to air, it become oxygenated.
