Can matter be found in a plasma state in the liver?

Answer 1

Only if you fell into a nuclear reactor, and then only for a short time.

Seriously... you are mixing up two different meanings of the word plasma.

In physics there are four states of matter: solid, liquid, gas, and plasma. Plasma is what happens when you heat something up very high. Start with a solid, heat it up till it melts. Now you have a liquid. Heat the liquid till it boils. Now you have a gas. Heat the gas until the molecules break down, now heat it more until the electrons have so much energy that they escape from the nucleus of the atoms. Now you have a plasma state. A plasma is like a gas, expect that all of the particles are charged.

In Biology plasma is a part of blood. If you start with whole blood then remove the red cells, the white cells, and platelets then you are left with a yellowish liquid. That liquid is plasma.
