[Harry Potter] What does Avada Kedavra actually do?

Does it sunder the soul from the body? Or does it do something else to cause death? 

And also it is said that it can't be blocked, but we do know that it will stop of it hit an object. Would transfigurating an object in front of it will stop it?

It makes you die. That's it, that's the tweet. It instantly terminates the biological functions of every cell in your body.

Removing the soul isn't immediately lethal-- case in point: the Dementor's Kiss. People who lose their soul become catatonic and eventually die of starvation/dehydration/exhaustion.
