Lecture for surgeons

So I'm going to be presenting a lecture at surgical grand rounds in a few weeks, on 'Endocrine Incidentalomas'.

 

I catch myself wondering, how much physiology would a surgeon really want to know? A colleague once jokingly told me all the physiology he needs to know is "Me cut, he bleeds"
 

After all, it's pretty impossible to talk about endocrinology without physiology, is it?
