First of all, if you haven't already, I suggest you look over the stuff in the anatomy wiki. It outlines the basics. Also, try http://www.soinc.org/anatomy_b, the 2012 training handout covers what you'll need to know.I am new to anatomy this year, and I am doing the digestive half of this years test (my partner is doing the respiratory). I was wondering what I should know to do well in this event. Also what do you recommend I put on the cheat sheet and what I should know for sure for the test. Thanks.
You should focus mainly on the different organs of the digestive system, what their functions are, and their histology. Especially for the stomach, liver, and pancreas, you should also focus some on the physiology, like the different secretions of each (i.e. cholecystokinin) and what their functions are.
I suggest you put a chart of the different hormones and enzymes associated with the digestive system, what their functions are, and where they are produced, on your resource sheet. I also recommend putting facts about the diseases (short description, causes, risk factors, symptoms, treatment) on the sheet too. A section on volcabulary won't hurt either.
Hope this helps.
