what are the
5 main body parts and what do they do?
I'm not sure how you are defining "body parts." Are you referring to the body systems, of which there are eleven?
Since this is not my area of expertise, I searched Google under the key words "body systems" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. If not, please repost in more detail. Thanks for asking.
