Though you definitely don't need to be reminded, an "organ" is a group of tissues that perform one function in the body.
Remember the range of organs in a body differ slightly for males and females, and they aren't necessarily internal. With that knowledge refreshed in your mind, go forth and name all the parts of you working overtime to keep you alive.
There are 78 organs in this game, but there are also additional points if you can name specific parts of those organs, such as the regions of the brain or the eye.
This list is based on Gray's Anatomy for Students by Richard Drake, A. Wayne Vogl ad Adam W. M. Mitchell (Third Edition).
