Human blood has red color when oxygenated which is mainly because of red blood cells. Its color changes to purple when present in oxygen deprived circumstances. To restore the color the blood has to be placed in oxygen rich environment.
Oxygen has hit the bood. Although the true color of blood is blue, when blood is exposed to oxygen it turns red.
Blue
Oxidized blood refers to blood that has been exposed to oxygen and has changed color from a bright red to a darker, brownish-red color. This typically happens when blood is outside of the body and begins to lose its oxygen content.
Blue. Your blood is always blue until it is exposed to oxygen, when it reacts and turns red. Since veins aren't exposed to air/oxygen, they remain blue :)
Any bleeding when the blood is exposed to oxygen turns the color of the blood to bright red and is called oxygen-rich. If the blood has used up a portion of the oxygen it is carrying, called oxygen-poor blood, it turns to a darker brick-red.
Colorless. No color. But when they are exposed to oxygen, it develops a blueish color. i say,Lobster blood is weird because it has no color............................................
No. Blood is bright red when it contains oxygen and dark red when there isn't a lot of oxygen. The blue you see in veins is the vein itself.
When blood lacks oxygen, it appears dark red or maroon in color.
No, blood is never blue. Blood is always red, even before it is exposed to oxygen. The misconception that blood is blue when deoxygenated comes from the way veins appear blue through the skin.
blood is originally blue but when its exposed to oxygen it turns red
Because blood contains(among other things) oxygen and iron. The iron reacts with oxygen and rusts, which is why dried blood is the color of rust. is it because the blood cells die ? cos that's what I've always though haha
Red blood cells are red because they contain a protein called hemoglobin, which binds to oxygen and gives the cells their red color. Brown blood may indicate that the blood has been exposed to oxygen for a prolonged period of time, causing the hemoglobin to oxidize and change color.
