Please excuse my poor english. This question might be stupid but i just think odd that the greek chose the liver which is the only organ that can actually grow back out of the entire human body.
Thank you very much
Add-on question: what did the ancient Greeks believe that the liver was for?
This question has mostly already been answered in this thread here
A combination of /u/FennyDrayton and /u/abutthole 's answers answer your question.
In addition to /u/abutthole's reponse from two years ago there's also /u/yazid87's more in-depth response from about a year ago.
