question about wordpress

Does anybody know how wordpress spits out the content, like I know that it renders the content by calling the query() function and stuff like that but I'm not sure where in the wordpress files it is located that controls all that. I just want to manage where everything goes inside my blog. I don't want a plugin though.

Thanks for the help...

Please be more specific with your question.

I'm sorry I just don't know how to ask the question but it's all good now, I got it. Thanks for the help anyways
