For comparison, normal atmospheric pressure - 760 Torr, and the pressure on the moon - about 10-11 torr. The blood boils at 47 torr. The body is inflated due to the fact that the fluid in the soft tissues passes into the gaseous state. However, the skin is strong enough to withstand this pressure. So, you do not tear apart, you just razduetes like a balloon.
7. As soon as the body pushes steam through the nose and mouth, and the content of fluid in the body decreases, you feel all the more cold. Mouth and tongue become icy.

Withholding the air squeezed out of the lungs in the chest, and through the damaged blood vessels penetrate directly into the bloodstream. And through the bloodstream air bubbles already spread throughout the body and can easily get to vital organs such as the heart and brain.
