Yes
oxygen is what makes your blood red... you may not know this but when your blood is not seen it is blue
Hemoglobin, when united with oxygen, turns bright red.
Veins are blue because the blood is poor in oxygen, arteries are red because the blood is rich in oxygen.
oxygen is the answer
No. Blood is bright red when it contains oxygen and dark red when there isn't a lot of oxygen. The blue you see in veins is the vein itself.
That's easy. When blood is in your body it is blue that's why your veins are blue. When oxygen meets the blood the blood turns red.
Blood never turns blue. It's been argued that it turns blue without oxygen, but this is merely a myth. The blue color you see is the color of the tissue that makes up your veins. Blood will however, take on a darker shade of red without oxygen, but it never goes anywhere near the color blue. If you would like to see for yourself, the next time you get a blood draw, or you donate blood, look at the blood in the tube. The tube is a vacuum (so no oxygen) and the blood does not look blue.
oxygen rich blood is red, while oxygen poor blood is blue. this is the reason that blood in your arteries are always red, and blood in your veins are always blue.
When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red.
oxygen makes blood red go read a science book
Oxygen has hit the bood. Although the true color of blood is blue, when blood is exposed to oxygen it turns red.
The red color of blood comes from the iron-containing molecule hemoglobin found in red blood cells. When hemoglobin binds to oxygen in the lungs, it appears bright red. When it releases oxygen to tissues throughout the body, it appears darker red.
