Are you asking about human bodies as conductors? Or something else?

It's not really. While a better conductor than wood, it would not fall under the category of "conductor". The resistance of the human body is around 1000 ohms, but it depends on the person and where the line of current is. Human bodies can conduct electricity, usually due to an abnormally high voltage causing a significant current. This is due to the presence of conducting metals in our body.

What about water?

Water doesn't conduct electricity either. However, due to the water molecule's high polarization, it can dissolve ions into positive and negative particles, which will conduct electricity. This is why salt water is a relatively good conductor.

It's salt water in the blood that conducts electricity. As someone said, the salt dissociates to make charged ions that conduct electricity. Liquids like carbon tetrachloride are very poor conductors.

Many years ago I saw an article on how to make your own electric arc welder. It told how to drop the voltage from an electrical outlet by using two rods in a bucket of salt water as a resistor. Moving the rods closer together decreased the resistance. Given the high probability of being electrocuted, it's better not to try it, but the theory is sound.
