The organ responsible for the two bowels is the kidney. The kidneys are in the orifices of the ears and the two yin, which include the anterior yin and the posterior yin. The anterior yin has the function of urination and the posterior yin has the function of excreting dross. The two yin include the anterior yin and the posterior yin, and the anterior yin has the functions of reproduction and urination. Although the production and excretion of urine is controlled by the bladder, it needs to rely on the qi and chemical functions of the kidney in order to be completed. The relationship between urination and the kidneys is very close. If the qi and chemical functions of the kidneys are not normal, you can see retention of urine (urine dripping or not being able to urinate) and difficulty in urination; if the qi of the kidneys is not solid, you can see loss of urine, frequent urination, and urinary incontinence. The back yin is the anus, which has the function of excreting dregs, and the excretion of feces is also related to the function of the kidneys. Therefore, it is said that the kidneys are in charge of the two stools. If you feel unwell, please go to the hospital.
