In my Thermodynamics course, we recently learned about the saturation pressure and saturation temperature of different substances -mainly water. As you know, the saturation temperature at which a substance begins to boil is specific to a fixed saturation pressure. Water only boils at 100 centigrade while at atmospheric pressure; increasing that pressure in a P-v diagram raises the energy required to start boiling water, while decreasing that pressure reduces it. (Albeit, the enthalpy of vaporization decreases with increasing pressure)

Why is it that only the fluids in the body evaporate, accounting for the swelling, while the human body itself remains solid whilst exposed to the vacuum temperature in a space environment?

Same reason the spacecraft hull doesn't evaporate.
