I've been bowhunting for nearly 25 years now. I feel I have a pretty good grasp of what a deers antomy is pertaining to where things are when I send an arrow through the animal. When I don't see the animal go down, I come home and collect my thoughts and give the animal time. I have this anatomy site in my bookmarks and I pull it up to review it and double check my thoughts. I'm glad someone took the time and posted the thread years ago so I could review it. I wasn't a newbie then when I bookmarked it. I think it's a great review and a reminder.
