My first job at the hospital where I worked for 25 years was in the Pathology Department. Containers full of organs (hearts,lungs,livers,eyes,etc,etc) were an everyday occurrence there.
But it was a major hospital affiliated with a well known medical school so they were,in fact,meant for medical research.
One of my relatives has worked as a full time RN in post-op recovery at a heart institute for decades. Years ago, he told me that he liked it because he doesn't have to deal with patients who talk back or complain. They are kept sedated for at least 24 hours after surgery to stabilize. Afterwards, if all is well, they get moved to other areas of the hospital and other nurses.
He also works part time at the Provincial Coroner's office. Those 'patients' also don't usually talk back or complain. As he gets older, one must hope that he doesn't get his roles in the different jobs confused!
Reminds me of an old joke. Someone answering the 'phone at the ME's office says, "County morgue. You stab 'em, we slab 'em!"
