Well, I don't know when your regional competition is, but this is kinda late in the game.
Don't worry, I was a newbie in 8th grade too.
To study for anatomy, there's not much you can do besides getting ahold of an anatomy textbook or two. You can search this stuff on the internet if you are capable with google, but internet material doesn't seem to cover the right stuff.
Try to just go through the sections about the digestive and respiratory system. You will also have so know quite a bit of physiology besides just the anatomy. You should dig a bit deeper than regular functions of the organs though, such as what kind of cells in the stomach produce pepsinogen or hydrochloric acid, and what kinds of enzymes the pancreas secretes (and what they're for).
The cheat sheet should include information like chemical equations or disease facts. Putting a labeled spirograph on the cheat sheet is a good idea.

im new to this whole thing...meaning anatomy...even tho im in 8th grade -.-
so
this year it's digestive and respiratory system
duz anyone have any suggestions as to what I should do to prepare and what to put on my cheat sheet?

if i cud get a quick reply
that would be really helpful

thankz,

What SciBomb said, but also check the digestive and respiratory wiki. They are really helpful.

If you are in a super-ultra-mega-hurry, then just try to memorize a little. Take, for example, just the oral cavity. Memorize everything about the mouth, teeth, tongue, etc. Then, you can put everything you didn't have time to memorize on your cheat sheet. It's pretty pointless to have stuff you already know on your cheat sheet.

For the respiratory system, you've gotta know the structures of the lungs, bronchial tree, and alveoli, as well as gas transport across the respiratory membrane. Also, Boyle's law, Dalton's law of partial pressures, and Henry's law are all good things to look up on google/wikipedia.
Differences between internal and external respiration is bound to be on any anatomy test.
Respiratory capacities and volumes (and a spirographs) will almost certainly be on the test too.
For the digestive system, at least know the liver, stomach, small intestine, and pancreas in detail. They are very important. You can put a diagram of tooth structure on your cheat sheet, no need to waste time on it is you're trying to hurry. Pepsinogen/pepsin, trypsinogen/trypsin, amylase, lactase, lipase, and bile are important chemicals.
Lastly, the parts of the brain which control different processes may be on the test, but that's also something you may want to put on the cheat sheet.

Get a textbook (preferably college-level). Read the chapters on respiratory and digestive. Memorize everything you can. What you can't memorize, put on your cheat sheet. Listen to what SciBomb says too. He knows what he's doing.

Thanks. It's very helpful.
Sorry for late question. I only thought of this a while back. xD

I'm done with my hiatus of editing the digestive wiki, so the in-depth descriptions should be completed by next week .

And then we went way in depth about pulmonary ventilation, and then the structure of the lungs. We accomplished this in about one hour, and this was the first Anatomy meeting...at this rate, we're not going to have anything to do by two weeks before Regionals.

My God, how did you do this on the first day? I couldn't even label all the diagrams that were on the test this saturday.
And how exactly does partial pressure work? There were about 10 questions on the test about it, so I did a random math until I got an answer that matched one of the choices.

Okay, partial pressure...
So, atmospheric pressure has a total value, right? That would be 760 mm (using a mercury barometer, of course). So basically what it is is that there are different gases that contribute to the total pressure. Each of these gases have a different pressure. Their individual pressure is called...you guessed it, partial pressure. So basically, if nitrogen makes up for 78% of the atmospheric pressure, then you multiply 760 by .78. That gives you the partial pressure of nitrogen.

so does this mean that if I put this into a proportional concept (setting the percentage of that gas in the atmosphere over 100, and opposite side of the equation with the atmosphere pressure under x), i did it correctly?
