Anatomy and Physiology Homework Help, can anybody answer any one of these questions?

Answering these questions for you would not help. The point of having to do them is to do your own research which facilitates learning. If you do your own work, you will remember it. If you don't, do not plan on making it to college. It will not fly at a University. You will also fail most of your tests. Smart people get that way because they do their own work. Asking for help is different than "Give me the answers because I am lazy."
