Human blood is iron based so it oxidizes red. Vulcan blood is copper based so it oxidizes green.

Blood is red because of the iron content. Blood is bluish-purple while in the veins (returning to the heart). When oxidized in the lungs (through the pulmonary artery), it turns red. Red blood is distributed to the various body parts through arteries. Once the oxygen is used, the blood returns to it's bluish-purple hue for the trip back to the lungs.

mr moppet is right partially..it is because of the presence of a pigment called heamoglobin in ur red blood cells. the pigment contains ferrous or iron what is known as heam and the globins are protiens.iron is present in the form of a complex molecule and hence the color. every substance that has elements of the d-block in the periodic table, have color and the color in this pigment in blood happens to be red because when exposed to light it reflects that wavelength of light.

Human blood is Blue before it hits the oxygen then it turns red.Look at your veins Blue not Green,unless of course you are an alien.

hey!!!who said that our blood is not green.......it is indeed green but inside our body.the blood inside our body is actually green.......but when u happen to cut ur finger or when something goes wrong resulting in bleeding,the green coloured blood immediately reacts with the atmospheric oxygen which turns it red.well!haven't u studied this in school?ohhhhhhh ok may be u are not a science student and hence this doubt!!!

Red blood cells are red only because they contain a protein chemical called hemoglobin which is bright red in color

human blood actually cantains red blood cells which are red in colour not in green.That's why human blood is green.

Years ago I was asking the same ?.The answer I got kind of thru me for a loop.I was told that in your body your blood is Green.It is until it hits oxygen outside of your body.
