why is it that the color of our blood is only one & one only ?

Answer 1

Blood is red because of oxygenated iron in the red blood cells. When it is deoxygenated it is a darker shade of red, slightly violet (commonly thought of as blue because of the color of veins beneath the skin).

Answer 2

"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 3

That is not true. Blood is red and blue. Oxygenated blood is red, while the one without oxygen is blue, look at your veins they are blue, whereas your arteries are red. The reason you only see red blood is because when you cut yourself your blood reacts with atmospheric oxygen. If there were no oxygen around your blood would be blue!.

Answer 4

That's because of red blood cells

Answer 5

i don't really understand your question but ... our blood is two colors. Red and Blue. Red with oxygen blue without.

Answer 6

If blood is oxygenated, meaning it has oxygen in it, it is red. If it isn't oxygenated then it is blue. that is why veins are usually blue in our body, and when we are cut it is red. depending on where the blood is located in our body, it can be red or blue.

Answer 7

Because unlike skin, blood is not exposed to the sun, nor is it different for people, as we are all the same inside.
