Are there people who actually have' blue blood'?

Question

instead of red?

Answer 1

It's not blue per say. It is a reference to royalty and nobility. Many royal houses in Europe intermarry. Many of them have been hemophilliacs. This means the blood does not carry as much oxygen as normal blood. That's why veins appear blue under your skin. They are lacking red blood cells full of oxygen.

Answer 2

There are - they have an illness called hemophilia. That means the blood can not coagulate within normal time-limit. Every little cut goes on bleeding and bleeding.... because there´s not the vital componend in blood that makes thrombocytes coagulate.
Nowadays this is perfectly treated, even sometimes it´s artificially provocated to avoid tromboses.
The illness is heritatet only from mother to son, never from mother to daughter (though she probably will have ill sons), and it is specially bound up with early aristocracy families in Europe as there was illness poping up.
The blue is relationed with the color body changes when there is a blood distribution problem, for example when you stay long time in very cold water all blood is retained in center of the body in an intend not to loose more temperature on surface, and efect you see in getting blue lips and fingernails, the same efect is when you have not enough blood after a big bleeding or heart does not work ok.
Blood is always red - in body it´s light red if it´s just oxigenated in lungs, little bit darker in veins and out of the body it gets brown (iron reacts with air).

So originally blue blood meant an aristocrat hemophile.

Answer 3

All people have blue blood, but not as coined to describe royalty. When blood picks up oxygen in the lungs, it becomes red. After distributing oxygen to other parts of the body and picking up the extra carbon dioxide produced, the blood takes on a bluish tint. Take a look at a pale person's arm, if you aren't. You'll find veins pretty easily, and almost all of the visible ones are blue-purple.

Hope that helps!

Answer 4

I can not believe the number of responders who think our blood is actually blue until (it comes into contact with air)! How utterly rediculous!!! As a dialysis tech I can assure you that blood is always some form of dark red. Get a grip people!!

Blue blood is an English expression recorded since 1834 for noble birth or descent; it is a translation of the Spanish phrase sangre azul, which described the Spanish royal family and other high nobility who claimed to be 'pure', free of Moorish or Jewish blood, being of Visigothic descent. There is no connection between the phrase and the actual blood color of nobility; however, in the ancient agricultural societies of Europe the whole upper class had superficial veins that might be more visible and appear bluish by comparison to the rest of the pale-pinkish skin, as the skin itself was not tanned. In contrast with the working class of the time (mainly peasants), nobility and in general upper class people did not have to work outdoors, and mostly lived sheltered from the sun by dwellings and attire. The same contrast could be observed between untanned upper class Europeans - especially of northern stock whose skin tends to be less pigmented - and all social strata of Mediterranean populations with higher levels of genetically determined skin pigmentation. An alternative traditional explanation, argyria (a disease causing a blue-grey skin tone after digestion of silver), is considered less valid as table silverware was not massively and regularly used by much of the nobility

And I cannot believe a kid in high school is gonna mail me privately and tell me that I'm wrong! Show me the studies! Until then I will base my answer on my own medical work experiences, thank you very much!

Answer 5

No. Blood is red due to the oxygen-bearing chemicals it uses. The de-oxygenated blood in the veins is mauve but would turn crimson if it was spilt.

Some theorists reckon in the old days royals did have blue blood, as they are not entirely human and genetic lines were purer then. By 'theorists' I mean people like David Icke.

In Hindu mythology a few royal characters, including Prince Rama, are often portrayed with blue skin.

(Just now) Blue? Purple? YELLOW!? When you donate it's from a vein (de-oxygenated) and it's definitely MAUVE.

Answer 6

Here's an easy way to debunk the myth about blood being blue until it meets with air. Ever had your blood taken? It shows as red in the tube despite having not met with any air.


So no.

Answer 7

Blue blood does not exist, I imagine you are refering to royal blood, which is said to be very pure and noble, back a couple of centuries they were the healthiest, people around, it is said because they used silver culturly and goblets, that they had blue blood

Answer 8

There is no human with blue blood.
Only color blood that humans have is red.

Answer 9

Yeah, so when u see ur veins, don't u see that it is blue? Thats the blood in it. All of us have blue blood but it becomes only red when it is exposed to air.

Answer 10

we all have 'blue blood' but it is only blu until the blood comes out of our body and oxygen combines with it... if thats what you mean (scientifically) sorry if its not
