Is our blood blue until the upper air hits it?


so they say but i dont really know
No. When you get blood drawn, it doesn't touch air, all the same it is red when it goes into the vial.

Blood is always red, but it change color slightly depending on whether it is coming from your heart bringing oxygen to the rest of your body or coming back to your heart from the rest of your body to get more oxygen. Blood surrounded by your arteries is bright red because it has oxygen in it and is carrying the oxygen out from the heart. Blood surrounded by your veins, which is deoxygenated, is darker red (almost purple/maroon) and looks blue through the skin.
Nope. it becomes red when the hemoglobin mixes with it. the hemoglobin give the color. and the appearance or the color of the blood is affected if its oxygenated or de-oxygenated
oxygenated; bright red
deoxygenated; looks like claret
Yes, our blood is the color blue inside our bodies. Once it hits the air or oxygen then it turns red. Don't you see blue vains when you turn your rist over but when you bring a cut and bleed your blood comes out red. Tada!
NO. If you have have your it was sucked into a vacuum. Air does not touch it look to see what color it is. It is generally misty red.
Oxygenated blood appears red, so arteries tend to be redder in tone (carrying oxygen out from the heart/lungs) while veins are bluer (carrying the oxygen-depleted blood and consume products back from the extremities to be cleansed and re-oxygenated). NO. If you have have your it was sucked into a vacuum. Air does not touch it look to see what color it is. It is generally misty red.
Blood which has simply been exposed to the air surrounded by your lungs will be red. It turns blue as it circulates back and looses oxygen. So, I guess the answer is, it depends.
it's not really blue, kind of a dark overcast red, almost black. You see blue veins because of the skin over your veins.
Blood next to oxygen in it is bright red. Blood which has simply been exposed to the air surrounded by your lungs will be red. It turns blue as it circulates back and looses oxygen. So, I guess the answer is, it depends.
yes
Yes, that's correct. The iron in your blood is what make the red color. The oxygen molecules bond with the iron in your blood, which make Iron Oxide A.K.A. rust. Actually it is more of a purplish-red, but the veins appear blue looking through the skin. So 'blue blood'.
Answers:    It is blue until it oxidizes (meets oxygen).
Then how come our face get red when blood rushes to it? so they say but i dont really know
in fact.de-oxygenated blood is blue (blood that is going to the heart) and oxygenated blood is bright red. it depends were you seize cut and if the the blood is de-oxygenated or not. thats why sometimes when you get cut the blood that comes out is bright red and in other ocations its a dark blueish color Yes, our blood is the color blue inside our bodies. Once it hits the air or oxygen then it turns red. Don't you see blue vains when you turn your rist over but when you bring a cut and bleed your blood comes out red. Tada!

Actually it is more of a purplish-red, but the veins appear blue looking through the skin. So 'blue blood'.
