PSA: Human blood is not blue

[HAL9000]

wtf

Left is blood in CO2 right is blood in O2

 

[Dumac]

No, it's blue when it's in your veins and then when it hits the air it turns red. Its called the Coriolis Effect. It's the same thing that gives Mars its color.

This is the thing I am tired of hearing. The New Zealanders/British know what's up.

Do people actually think that?

The coriolis effect is to do with the curvature of the earth.

Yes. It is a terribly false bit of information that people hear as a kid and cling to for dear life.

It takes hours to convince most people that they are wrong. The idea is deeply entrenched into their minds.

Most people don't think it has anything to do with the coriolis effect. They just think blood - oxygen = blue, and blood + oxygen = red, partially due to the circulatory system diagram that draws the tracts and blue and red plus the appearance of veins in skin.

Insanity.

I think your sarcasm meter is broken.

I think your sarcasm meter is broken.

Honestly so many people have been convinced that blood is blue, I have no way of telling when people are joking.

The coriolis effect has to do with the spinning of the earth, not the curvature.

Good point. I stand corrected

God damn I fucking hate Voyager. No meme should ever come from it, other than about how something sucks ass.

Meh it wasn't great but it's better than DS9

 

[dawp]

nvm

 

[JTsyo]

Yeah, I meant human blood. Sorry for the ambiguous thread title.

I'm just tired of people swearing to me that human, oxygen-deficient blood is blue.

Then why does your face turn blue when you don't have air?

burn him!

 

[Raizinman]

I always wondered why; when a nurse removes blood with a hyperemic needle, the blood shows up as red in the vial. If there is no oxygen in the vial, shouldn’t the blood come out blue?

 

[Bateluer]

So, what color is a Vulcan's blood. Its copper based, and appears green in their veins. What color does it appear to be when comes into contact with O2?

 

[Pheran]

Meh it wasn't great but it's [Voyager] better than DS9

Gigantic FAIL!

How is it possible to be alive, sentient, and not know this within a few years of leaving middle school?

OMG Mars is made of Blood?!?!

/facepalm

Blood is never ever blue, never has been blue, never will be blue. It's dark red, or lighter red. Thats it.

That pic caption really needs to be updated, then put side by side with this one:

I wonder if they're the same guy... :hmm:

 

[Worthington]

that's what he's saying.

Duh, haven't you ever played any of the Doom games? Mars is a fucked up place.

It's a chop, I can tell by the pixels...
