Is deoxygenated blood blue?

[Guest]

The Magic School Bus quite clearly showed that deoxygenated blood is blue. How could you argue with Ms. Frizzle?

[MarbleZone]

You DO realise that hemoglobin contains oxygen anyway' date=' right? And that without that oxygen, the hemoglobin wouldn't be hemoglobin anymore, right?

Oxyhemoglobin carries oxygen and is red, deoxyhemoglobin is free and is blue/purple, not black.

 

Also, if I did that experiment, the blood would clot. That is unrelated to a state of hypoxia. :/

[Metal Skull]

It's purple-ish i think, I remember my science teacher saying that, but I might be wrong.

Blood that has not been oxygenated is dark red, not blue. The blue is just a visual representation so you can tell the difference between veins and arteries.

Time to school you all...

 

The lungs gain oxygen, which is sent to the heart to oxygenize the blood to be distributed, (mostly to the brain), which is then sent through the arteries, and when it delivers oxygen and nutrients, it becomes bluish-purple, because hemoglobin in the blood becomes red when carrying oxygen, and the bluish-purple when not.

Uh... no. The only one who needs "school" is you. Go back to biology.

[~ P O L A R I S ~]

My veins're telling me a bluish-green. Hope that's just the lighting or something.

[Dark]

Ehh, let's see what I remember from freshmen year bio class. And let's try not to Wiki-cheat.

 

Blood is red once it comes in contact with oxygen.

 

Blood is a darker shade of red (but not necessarily blue) when it has not been in contact with oxygen.

 

This is why when you cut yourself, the blood is red.

 

However, the theory is that your blood is blue because of your vein color. But explain why your blood is dark red when they take a blood test.

 

But there was something about how poisonings (of multiple kinds) can alter the color of blood.

 

Yeah, I suck at bio. D:

According to your post you don't.

You do know that oxygen is in the air, so when you cut yourself, oxygen gets in your hemoglobin...

I thought that was common knowledge.

 

Blue and red seperate veins from arteries in an anatomical picture, but I'm not sure which color is connected to which. I think red is arteries and blue is veins.

 

And bio is my least favorite science class. Physics all the way!

Nice counterproductive response, though.

purple - bluish.

ITT: Dark believes that there is no air around us, and if there was, it doesn't contain oxygen.

You have to be making this up as you go.

 

Honestly, you're waving your ignorance around like a banner. I have nothing against people being wrong on a subject, I'm off on a lot of stuff, but seriously... "When you cut yourself oxygen gets in your hemoglobin"?

[HeadshotMagnet]

Heres why ur blood is red when you get a cut and bleed:

 

Your blood is naturally red when in contact with oxygen. The blood carries oxygen throughout the body. When blood runs out of oxygen, it loses color, like its dying. The only way to get more oxygen is to go to the lungs to pick up the oxygen you breath in. The blood carries Carbon Dioxide out of the cells and into the lungs to get rid of it and replace it with oxygen. The only way it turns red is when it comes in contact with oxygen, thts why ur blood is red when you have a cut and why unoxygenated blood is purplish-red. Not quite blue tho.

That is exactly what I said. Be prepared to be made fun of as ignorant.

 

Just because you put it in more words, doesn't mean it's different. If I'm wrong than he's wrong, too.

[~ P O L A R I S ~]

Oh, so what you guys're saying is that I'm the only one whose seeing green in their veins?

 

Y'know what, funk you guys man you all totally see green in your veins you're just denying it.

Blood does not turn red when in contact with air. Hemoglobin transports oxygen intracellularly - coming into contact with air doesn't change anything at all.

So yes, he's also wrong in that regard - the exception is, he wasn't being arrogant about it, he's just not right.

 

Polaris, you see your veins blue/green because of light absorption properties of subcutaneous fat. It has little to do with blood colour.

Exactly.

[Felix Culpa]

And back to Dark's question:

 

When you donate blood, they do not take deoxygenized blood from your veins, but the blood from your arteries, which has not yet been delivered to cells, so it is the normal red-scarlet color that you normally see blood.

 

At Black Wind:

v.v You really do not have that much of a knowledge about this, do you? Sorry to point this out, but once hemoglobin touches oxygen it absorbs it, giving it the scarlet color you see when you cut yourself. It doesn't matter if you cut a vein, once you cut the vein it will turn red because oxygen touches the hemoglobin, and then is absorbed "inflating" the cell.

[Dark]

Why don't we ask CP for the answer to who is right?

 

Because I can assure you a majority of this is copy/pasta from the Internet.

Like I said, hemoglobin is intracellular. It cannot "touch" atmospheric oxygen simply in contact with air.

Trust me, I do know a tiny bit of what I'm talking about.

Also, blood for transfusion is actually taken from veins.

[Felix Culpa]

okay, so we can all agree on the topic question that deoxygenated blood is not blue. Okay, then. So we are done.
