ELI5: what happens to your body when you get an electric shock - is the electricity just passing through you?

Yes. Yes it is. 

Electricity passing through you is just electrons moving. When they move in conductive (but not superconductive) objects, they pretty much interact with nearby atoms/molecules as they travel through.

Think of having a bunch of marbles on the floor, and rolling one small marble through them really hard. That small marble will hit the other marbles, right? Well, electrons behave similarly. This is what "impedance" is like.

Every time the electron hits a point of impedance, it releases energy. Picture being one of the marbles that you just hit with the small one. It would make a sound, right? The sound is the release of energy. Well, electricity works the same way, except at a much smaller (atomic) scale and the result is what is called "joule heating".

With enough current running through your body, the amount of joule heating that occurs can be fatal, and you'll burn up.
