why does your blood turn red when it hits oxygen?

Answer 1

Ya mean,,,change from the "blue" color it appears to be when it's in our skin??

The Blue color is a sorta optical illusion,,,the light is filtered by our skin and makes it look blue.

Blood is always Red,,,even if it doesnt appear to be .

"FAQ- Why do your blood vessels look blue? Is the color of blood inside the body really blue? Does blood turn red when it hits oxygen outside the body?

Here is the statement of the American Society of Hemotology in Washington, DC, in the Jan 2003 The Science Teacher Journal :

" Contrary to popular belief, the color of blood inside the body, no matter how you look at it, is red.
Blood is bright red when oxygenated and dark red when it lacks oxygen.>>>>>>>(cont) "

Answer 2

Guh, I hate when people think blood is blue when inside your body. Blood is always red! When it's in your body, it's a darker red though. When it hits oxygen, it has a chemical reaction which lightens the colour a bit.

Answer 3

Because the hemoglobin in the blood cells that carries the oxygen changes color with the chemical change of absorbing the O2, from a dull bluish tone to red.

Answer 4

blood is red because of the red blood cells, or hemoglobin. when hemoglobin is in the presence of oxygen it "picks up" the oxygen. the oxygen is later detached from the hemoglobin when it reaches an area of the body with a need for oxygen. blue, or venous blood, is lacking oxygen. red, or arterial blood, has nearly fully loaded hemoglobin present.
