Are parts of our blood blue?

Answer 1

No. Deoxegenated blood gets oxygen when it gets to your heart and lungs (that is why we breathe -- so we can get oxygen to our blood). This is where it turns the bright red color that we see it. Then it leaves through your arteries to get to where it is needed. After all its oxygen is depleted, it turns dark red and heads back to the heart and lungs through your veins (as opposed to your arteries) to get oxygenated again. People say it is blue because it looks blue through the walls of your veins, but it isn't true. It is just darker red.

Answer 2

If parts of blood is blue, and only terns red when it hits oxygen, then why is it red when it runs up an IV blood draw up into an airtight tube?

No blood is not blue, it only looks that way on the outside of our body, like at places where veins show at the hand, wrist, bend of the arm, etc, due to the color of veins and arteries. These are what makes it appear that blood inside our bodies is blue. Which it isn't. This is a wide spread myth which has been properly dispelled.

If you take a look at a chart showing veins and arteries you will see them colored blue. It is not the blood inside which is colored blue, it is the outer skin or material of the veins and arteries which is this color. The color of the container does not affect what the container holds. Makes since right? That is because it is true.

Hope this helps, have a nice day.

Answer 3

I've seen lots of blood and never seen blue blood yet. Venous blood is darkpurple-red - sort of like dark cherry and arterial blood is brighter red because of the difference in oxygen. Veins are blue but the blood in them is red. The little cells floating around in the fluid are red. The fluid (plasma) is yellow. People of all races have red blood. You cannot tell the color or religion or race of a person by the color of the blood. We all bleed red. Some medications can make some differences tho - a person with a lot of triglycerides in there blood will have blood that looks like cream of tomato soup because of all the visible lipid.

Answer 4

Your blood is blue when the oxygen it is carrying is expended to the various parts of your body; then it returns to your heart and lungs to be reoxygenated. The reason it always appears red when you bleed or give blood is that it takes the oxygen from the air.

Answer 5

The red color is coming from the hemoglobin, an iron containing
protein in the red blood cells.

It appears blue, because it doesn't get alot of oxygen inside of the veins.

Answer 6

Yes. Blue blood is just blood lacking oxygen. As soon as it reaches the lungs though, it turns red.

Answer 7

Our blood appears blue underneath the skin because that's what it looks like when it's not exposed to oxygen. Once it gets out, it's red.

Answer 8

Human blood is blue before it becomes oxygenated.

Answer 9

I heard that once....that our blood is blue until oxygen hits it and then it's red....so when we bleed, it's always red because when it comes to the surface of our skin, oxygen hits it. DOn't know if that's really true or not, though.

Answer 10

No. It just looks that way because it has oxygen in it and that interacts with hemoglobin (blood), much like the way the sea and sky look blue because of all the elements that interact with the water and atmosphere.
