What is the correct order of what happens to your body in space without a space suit?

The vacuum of space will pull the air from your body. So if there's air left in your lungs, they will rupture. Oxygen in the rest of your body will also expand. At most, an astronaut without a suit would last about 15 seconds before losing consciousness from lack of oxygen. (That's how long it would take the body to use up the oxygen left in the blood.)
