Conduction is the transport of charge, and it doesn"t issue what the fee carriers are. In metals the fee carriers are, together you say, the conduction electrons. But in electrolyte solutions prefer saline the conductors room hydrated ions prefer $\textrmNa^+$ and also $\textrmCl^-\;.$
As far as power is concerned our bodies space basically just dilute electrolytes, for this reason the (rather low) conductivity the the person body is due to transport of ions.
You are watching: Is the human body a conductor
You mention conduction in nerves. This is a little of a distinct case because the main action of nerves is no to conduct electricity yet to propagate changes in electrical potentials. Describing the mechanism through which nerves work-related would be turn off topic here yet is conveniently Googled.

Google it and also you will certainly get great answers for example :
PURE WATER DOES not CONDUCT ELECTRICITY. It"s every the salts and impurities in that that cause it to lug current. Skin is in reality a very an excellent insulator too so, family member to metal, human beings aren"t very great conductors. However, the is points such together the ionized water and whatnot that comprise our body that do reason us to conduct.

Actually the human body is not also good. The is the factor that you obtain a shock together your body is a resistance no in fact a pure condutor. If you get an ordinary power multimeter and test her restance indigenous one hand to an additional you will check out that that is in truth quite high. That is reason that girlfriend cannot feeling 12volt. Currently when the body surface is moist then you get a greater contact area and the body resistance will drop therefore putting a battery across your toungue root cause a tingle.
Humans room actually awful conductors. The common resistance of any human is about 6 Meg Ohms. Copper is only a couple of ohms (depending on the length). Yet we execute conduct because we room 70% water, (though pure water no conduct electrical power either.)
