Functions of the Kidneys
The Kidneys govern water.
Commentary: The Kidneys are like a gate that opens and closes in order to control the flow of Body Fluids in the Lower Burner. A correct balance between Kidney Yin and Kidney Yang results in the correct regulation of urination. The Kidneys provide Qi for the Bladder to store and transform urine. Blood Deficiency, Body Fluids Deficiency, Dryness or Dampness is determined. The Kidneys receives fluids from the Lungs, some of which are vaporized, and send them back to the Lungs in order to moisten them. Kidney Yang provides the Spleen with the heat it needs to carry out its function of transporting and transforming fluids. In the same way, Kidney Yang is responsible for the body's metabolism.
