I always figured that you wouldn't explode, but simply 'disassemble'. It was my understanding that the human body is held together under of the pressure of the atmosphere. So, if you remove the atmosphere, what is holding the body together?

Mount Everest is 1/3 sea level pressure and while you can't breath up there your not at risk of poping. The reason for this is a combination of things, the skin is tough stuff, but also your insides also resist expansion. Down to the cellular level where osmotic forces can be stronger than a pure vacuume.
