According to the result about 'San Jiao(三焦)'recorded on "Yellow Empero's Canon Internal Medicine Ling Shu(黃帝內經 靈樞)", we achieved following results. 1. As we consider the concept of 'San Jiao' recorded on "Ling Shu", in early time, it was related to bladder(膀胱) and there was no divided concept into 'Shang Jiao(上焦)', 'Zhong Jiao(中焦)' and 'Xia Jiao(下焦)'. Later, there was appearance of body metabolism concept in anatomic way and started to emphasize that stomach(胃) is the very beginning of digestion. This point then adjusted into the concept which the core theory of digestion and water metabolism begins with 'Zhong Jiao' and processes to 'Shang Jiao' and 'Xia Jiao' then it established the 'San Jiao' theory adjusted to the functional change than property change. Later as there is set theoretical structure of 'three Yin and three Yang(三陰三陽)', it included the concept of 'San Jiao' onto meridian system theory to complete as a theory. Finally, it completed the theoretical structure that 'San Jiao' runs water metabolism of circulation, body fluid and urine for body to produce blood and Qi to protect and provide nutrition to the human body. 2. From the point of each part, 'San Jiao' means all body composition factor related to the relation to the digestion and water metabolism to produce Qi and blood. Also, the details of entire function of 'San Jiao' tells that 'Zhong Jiao' intakes food and divides the clarity and turbidity of digested substances. The origin of this digestion and water metabolism lies at Xia Jiao. The clean substance including the mood and taste climbs via Shang Jiao. The vapor like substance climbed to Shang Jiao becomes 'defensive Qi(衛氣)' and controls body temperature and sweat by supporting and spreading the Qi by Shang Jiao. The liquid substance climbed to Shang Jiao becomes blood. The blood has stronger character as substance than defensive Qi so Zhong Jiao becomes the base and the way for the blood. The turbid Qi separated at Zhong Jiao passes large intestine and the solid substance is excreted and the liquid is absorbed into bladder. The Xia Jiao that controls this process controls the liquid state of water matabolism so control the urine with bladder. Therefore, 'San Jiao' can be understood as a general concept that controls entire water metabolism as a way of food, Qi and blood.
