Functions of the Kidneys
The Kidneys control the lower orifices.
Commentary: Urethra and anus are the lower orifices, which are functionally related to the Kidneys. The Kidneys govern the functions of holding, opening and closing the urethra and anus. If the Kidneys are weak, urine may leak out causing dribbling urine, incontinence or enuresis. Since sperm is the outer manifestation of Kidney Essence, a weak Kidney energy can also lead to nocturnal emission and seminal emission. Losing control over the urine or stools, which may happen during shock, can be viewed as a dysfunction of the Kidneys. Kidney Yang has to be strong in order to control the lower orifices correctly.
