Question

Is blood blue or red inside your body???

Answer 1

both

blue has no oxygen

red has oxygen

that why when you get cut the blood is red because it reaches oxygen

Answer 2

Deoxygenated (without oxygen) blood is dark blue. Carbon dioxide and other wastes in the body make our blood cells this color. Oxygentated blood is oxygen attracted to the iron atoms in the center of hemoglobin. The same principle that makes rust red is what makes your blood cells red, also.

Answer 3

Come on

Your Ignorant people

You say that you blood is blue inside your body cause there is no oxygen.. This is not true

The purpose of the red blood cells is to carry blood through your body so how can it be lacking oxgyen... Blueish greyish is the color of your veinss. it is really sad to know that people think this way

Answer 7

Answer 8

As it was taught in 3rd grade science, its BLUE in your Veins and Red in your arteries.

Answer 9

It's not blue it's really dark red, (blue..... that's like alien blood.) When it hits oxygen it brightens in color.

That's why sometimes when you bleed your blood is darker and sometimes brighter.

Answer 10

In humans and other hemoglobin-using creatures, oxygenated blood is bright red. 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 venous blood is blue before it is exposed to air. Another reason for this misconception is that medical charts always show venous blood as blue in order to distinguish it from arterial blood which is depicted as red on the same chart.

Answer 11

It's blue. It doesn't turn red until it hits surface and gets oxygen.
