Since this thread has become a bit about c/s research.. thought I'd ask some questions that I've often wondered on how it works. Is -anything- passed through the vagina at all? eg.. the placenta? or is this removed same time as the baby? How exactly do they get the placenta to come away? Is there a risk of the uterus contracting while you're still 'open'? I'm assuming lochia is the same when the uterus contracts after the birth?

Just curious
