TCM holds that the human body realized the integral connection by taking the “heart” as its master and the five storing viscera as its center associated with the six excreting viscera, formal body and organs and the orifices, through the connection of the meridians and the flow of qi and blood, etc. And this connection has a unique rule, i.e., one storing viscus, one excreting viscus, one body and one orifice to constitute a system.
