How is the organ system organized?

Not sure what that means.

I think you are asking a different question than you phrased. Are you asking how the monetary system (e.g.., Federal Reserve, Treasury, interest rates, that sort of thing) is organized?

If you are truly asking how the free market economic system is organized, well the answer is that it isn't. It's the result of millions of people making billions of decisions that they consider to be in their best interest. These decisions and actions send "signals" to others. I'd be happy to go into this further if this is the question you are asking.
