What is the colour of blood ?

Question

Red ,Blue,Sea Green ,White

Answer 1

Okay guys, no offense but I think my answer will be right. To the asker, you can even search this to the net. And I’m a science genius at my class so I know the right one. NO OFFENSE!

There are three colors of blood as I know. The colors red, blue and white.

The red color represents the deoxygenated blood. The blue represents the oxygenated blood and the white color represents the white blood cells. Thus, the red shade of blood represents the veins and the blue shade represents the arteries. And the white is for the white blood cells which fight infections.

To the asker, try to search this at Google! You will find that I’m right! :)

No offense okay?!! If you will give me a thumbs-down, I think that’s not very right anymore :(

I hope it helps!! :)

Human blood is Red. (It is never Blue, no matter what anyone says, there is ALWAYS traces of oxygen in it.  It can appear a dark red, even a purplish, but never blue.)

Answer 5

RED

Answer 6

Hold On, Is It Not Meant To Be Purple??

Answer 7

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.

The blood of horseshoe crabs is blue, which is a result of its high content in copper-based hemocyanin instead of the iron-based hemoglobin found, for example, in humans.

Answer 8

there is no "sea green" blood in humans. Blood is bluish when in the body because there is not enough oxygen exposure to make it turn red, like how you would see it if you cut yourself. I don't know where you got "white" but there are white and red blood cells

Answer 9

Blood is either blue or red, since some blood in the body is oxygenated (making it red) and some is deoxygenated (blue).

Answer 12

If you are talking about human blood, there is only ONE answer. Ignore all those people who say blood can be blue. That is an incorrect but common misconception. Oxygenated blood (arterial) is bright red, deoxygenated blood (venous) is a darker brownish red.

Veins can appear blue under the skin, but that is the color of the outside of the vein seen through skin. It you cut into the vein (!) RED blood will come out.

If you have ever seen a bag of blood used for a transfusion on TV, or given blood at a blood drive, you will have seen venous, deoxygenated blood -- it is RED.

Sure, there are red blood cells and white blood cells but you cannot see them without a microscope. And once you start talking about insects or other species you find other colors of blood, such as the blue hemocyanin-containing blood of crustaceans, but human blood is red, and nothing else.

Answer 13

human blood is red as is the blood of all invertebrates.  It is a dark rusty red in the veins where oxygen is low and a bright vivid red in the arteries where oxygen is high.

However insect blood is yellow and the blood of other invertebrates depend on what type of organism they are.

Answer 14

Believe me my wife is cold blooded and it is almost colorless (transparent) blood. When you prick her finger, all you get is transparent mucous like thing.....!!

Answer 15

Blue............ then when it mixes with oxygen it then turns red.
