start here http://www.innerbody.com/htm/body.html this is the best site I have ever seen for the human anatomy http://www.bbc.co.uk/science/humanbody/ these sites are just to give you a head start, you could probably use them all year long since this is what the class is about. As for all of your questions I can’t answer them but what I will say is take a wait and see approach, it might not be what you think, you just might like it and do very well in it. Give it a chance and wait for your teacher to direct you when you are not sure what to do next. Don’t be afraid to ask questions.
