Acupuncture theory and all Natural theory state KIDNEY and URINARY BLADDER form the WATER element of human body. Reproductive systems are also included with WATER element.
The KIDNEY located at the either side of the lumbar area is connected internally and externally with URINARY BLADDER and SEXUAL ORGANS
Its main Physiological functions are storing essential substances and dominating human reproduction, growth and development; producing marrow which collects in the head forming the brain, dominating the bones and manufacturing blood; dominating body fluid, and Receiving qi.
1. Storing essence and dominating reproduction, growth and development.
The main essence of the KIDNEY is of two types congenital essence inherited from the parents and acquired essence transformed from the essential substances from the food.
The vital essence of the KIDNEY greatly influences the process of birth, growth, full development and senility.
• KD 5 and GB 20 carry out this function.
2. Producing marrow, forming up the brain, dominating the bones and manufacturing blood.
The KIDNEY stores essence which can produce marrow including spinal cord and bone marrow.
The upper part of the Spinal cord connects with the BRAIN, while the bone marrow nourishes the bones and manufactures blood The supply to the BRAIN, the solidity of the bone, and the adequacy of the blood are therefore all closely related to the condition of the essence of the KIDNEY.
• KD 3 and SP 5 carry out this function
3. Dominating WATER metabolism
The part of fluid sent down by the descending function of the LUNG reaches the KIDNEY. There it is divided into two parts, clear and turbid, The clear part(which is useful) is retained, and the turbid fluid (waste part) flows into the URINARY BLADDER to form urine to be excreted .
KD 2 and TW 2 carry out this function.
4. Receiving Ql
Respiration is accomplished mainly by the LUNGS, but the KIDNEY helps through its function of controlling reception of QI(AIR). The distribution of clean QI(AIR) inhaled by the LUNG to the whole body depends not only on the descending function of the LUNG but also on the KIDNEY'S function of reception and control.
KD 7 and LU 5 carry out this function.
The KIDNEY opens into the EAR The auditory function is dependent upon the nourishment from the Ql of the KIDNEY. Deafness in aged people is mainly due to deficiency of the Qi of the KIDNEY.
