ah dang... organism doesn't sound right? shoot.

My dictionary says it's a body which is made up of organs... it looked OK to me. aaaaaaaaaahhhhhhh! I hate that my vocabulary is so limited!
How does "system" sound instead? Would that be better?
Thanks for pointing these things out to me, btw, I really appreciate it - don't hesitate to correct me when I'm wrong, it's always helpful.
