You mostly hear about electrons as being the vehicle of an electric current because we think of wires and metal. However, if an electric current traveled through the human body, it would be in the form of ions, right? But what happens at the interface between body and wire? I am guessing that if the electrons in a current of a wire contacts flesh, there must be some kind of oxidation/reduction occurring at that point and also when the current leaves the body to go to Earth or another wire. Is that correct? So, if electrons pass into my body, the electrons may attach themselves to positively charged potassium or sodium ions, converting them to metallic potassium or sodium atoms? Would these metal atoms then give up their electrons at the exit point of the body as they transfer those electrons into the wire or into the earth? Or would some of the negative ions such as sulfate, phosphate, chloride, pass their electrons into the exit point, forming dissolved gases such as sulfur trioxide, chlorine, etc.? Since free electrons don't travel in fluids as they do in metal, this is the only explanation that I can envision.
