why is blood plasma called a plasma?

Maybe a history of WHY it is called a plasma and misleading people like me?

A plasma is a gas (or, I guess a liquid, at high enough pressure or.. cause of other properties..?) witch has its electrons separated from the rest of the atom, witch is now a ion. So it is a mixture of free electrons and ions.
Is blood plasma really this? I cannot find any information on this specific question anywhere. :(

Plasma was first identified in a Crookes tube, and so described by Sir William Crookes in 1879 (he called it "radiant matter"). The nature of the Crookes tube "cathode ray" matter was subsequently identified by British physicist Sir J.J. Thomson in 1897, and dubbed "plasma" by Irving Langmuir in 1928

In the late 1930s and early 1940s, Dr. Charles R. Drew's research led to the discovery that blood could be separated into blood plasma and red blood cells, and that the plasma could be frozen separately. Blood stored in this way lasted longer and was less likely to become contaminated.

“We noticed the similarity of the discharge structures. (…) Langmuir pointed out the importance and probable wide bearing of this fact. We struggled to find a name for it. For all members of the team realized that the credit for a discovery goes not to the man who makes it, but to the man who names it. Witness the name of our continent. We tossed around names like ‘uniform discharge’, ‘homogeneous discharge’, ‘equilibrium discharge’; and for the dark or light regions surrounding electrodes, names like ‘auras’, haloes’, and so forth. But one day Langmuir came in triumphantly and said he had it. He pointed out that the ‘equilibrium’ part of the discharge acted as a sort of sub-stratum carrying particles of special kinds, like high-velocity electrons from thermionic filaments, molecules and ions of gas impurities. This reminds him of the way blood plasma carries around red and white corpuscles and germs. So he proposed to call our ‘uniform discharge’ a ‘plasma’. Of course we all agreed.But then we were in for it. For a long time we were pestered by requests from medical journals for reprints of our articles.

If I am to trust this site, it seems the biological version came first. The story looks made up but I couldn't find anything else regarding this.

Interesting. It's in a letter from nature, I'd be prepared to stake that it was true (or at least as true as we are going to get).

well. that is really unsatisfying.
But thanks..

The term 'plasma' for the liquid part of blood dates from 1845; that for a gas of charged particles from 1928:

If you dislike various unrelated things having the same name, you should probably take up a language other than English.

You mean like fly (the insect), fly (like a bird), fly (as on pants), fly (as with flee), fly (as in flywheel), fly (as in the edge of a flag) and more?

Yes, but that doesn't help the OP understand the reuse of the word.
