Is blood red , blue or black?

Question

When air hits it is red but before it comes out , or is exposed what color is it?

Answer 1

In humans and other hemoglobin-using creatures, oxygenated blood is a bright red in its color. This is due to oxygenated iron in the red blood cells. Deoxygenated blood is a darker shade of red, which can be seen during blood donation and when venous blood samples are taken. However, due to an optical effect caused by the way in which light penetrates through the skin, veins typically appear blue in color. This has led to a common misconception that before venous blood is exposed to air it is blue

Answer 4

blood is blue before it hits the air. the oxygen turns blood red.

Answer 5

Blood is blue until he comes in contact with oxygen which makes it have its red color.

Answer 6

Well, it's always red, but if you cut a vein (I could be wrong...), because the blood has given oxygen to your cells, it turns a more bluish colour.That's why some of your skin looks blue, because of the deoxygenated blood.

Answer 7

The blood coming from the lungs with oxygen is red, flashy red. The "dirty" blood returning to the heart and the lungs is indigo (blue).

Answer 8

The color of blood depends on the chemical property of the atom that carries the oxygen.
In humans, the iron center of the heme group in hemoglobin is the oxygen carrier, and it is what gives blood its reddish hue.
In insects, on the other hand, the atom that carries the oxygen is copper, which is what gives their blood a bluish hue.

Answer 9

blue when its inside when it hits the air its red

Answer 10

no oxygen-filled blood is blue and oxygen-filled blood is red
