concerns about A & P!!!!!

You are going to find that no matter how much you learned in your classes. . .no matter how much more you learned doing some more reading and studying on your own. . .it will never be enough. You should be teaching yourself more than your instructor did. Your instructor is only there to guide you in getting started. If you can't find the answers to your questions on your own in the course of your lifetime, how do you think you will make it through Life 101? You can't rely on an instructor every time you need to make a decision about something. Educators are primarily passing on their wisdom on to you. Wisdom is a very subjective thing and the wisdom each person you meet is going to have is going to be different from someone elses. You want to be exposed to as many different people's wisdoms as possible. The purpose of going to school (besides the obvious one of learning some facts) is to learn about the resources available to you to find answers on your own. If a college manages to do that for you, then your tuition was well spent.

If you want to get some more information on Anatomy and Physiology I recommend that you go to the library or do a web search for "anatomy", "physiology" or "anatomy and physiology tutorials". You will learn much more about it than if I do this for you.
