I think the above poster is partly right. Based on what we've seen, weaker ghouls have basically the same weak points as humans when targeted with a quinque: brain, eyes, throat, heart, internal organs, plus their kakuhou. We've seen them dropped pretty fast when their vitals are hit.

Stronger ghouls, on the other hand, are vastly more resilient. We've seen then sliced in half, pierced through stomach, chest and skull, decapitated, and still live. I don't think it's a matter of them making spare organs as much as it is the sheer speed of their automatic regeneration. It begins to repair the moment the damage is incurred and prevents further symptoms like blood loss in the process. We can infer that because we saw it malfunction when Amon impaled Kaneki, and Kaneki panicked because the regeneration didn't proceed like it normally would by stitching up the damage which led to blood loss and shock. Same with Ginshi.
