1, Physiology and Pathology of "Large intestine governing body fluid"
The large intestine belongs to the six fu organs. As the "official of conduction", the main function of the large intestine is to pass on the dregs, alternating between deficiency and excess, and being in a state of fullness but not fullness, so as to smooth the discharge and use it for communication. Whether the function of the large intestine to transport dregs can be exerted normally is based on intestinal lubrication, and intestinal lubrication is also inseparable from the function of the large intestine to control body fluid. Modern research shows that the intestine is an important place to absorb water. About 65,438+0-2L water enters the colon with chyme, but the water contained in feces is only 65,438+0.50 mL, and most of it is reabsorbed by the drying of the large intestine. If the function of the large intestine regulating body fluid is abnormal, the water in the large intestine cannot be absorbed, and the water and dregs come down, there will be symptoms such as bowel sounds, abdominal pain and diarrhea; If the large intestine is really hot, it will dissipate body fluid, or if the large intestine is short of body fluid and the intestine is humid, it will lead to constipation.
2. The relationship between the function of lung and waterway and the function of large intestine in regulating body fluid.
The functions of lung water diversion channel and large intestine fluid supplement each other in physiology and affect each other in pathology. On the one hand, the lungs declare descent, disperse body fluid and moisten the intestines; On the other hand, the lung is connected with the waterway, which can balance the body fluid, ensure the dryness of the large intestine, and make the slag guide function of the large intestine play a normal role. The large intestine has the normal function of regulating body fluids. On the one hand, the reabsorbed water is input into the heart and lungs to promote the spread and decline of the lungs. On the other hand, it ensures intestinal lubrication, stool formation, unobstructed viscera and normal operation of lung qi. Pathologically, the invasion of exogenous pathogens or the depletion of lung qi will lead to the failure of the lung to pass through the waterway, and the pathogens will move down, further affecting the conduction function of the large intestine and causing constipation or diarrhea. Abnormal function of body fluid in large intestine, imbalance of water and fluid metabolism and obstruction of fu-organs and qi will also affect lung and qi function, leading to cough and dyspnea. Therefore, body fluid metabolism plays an important role in the theory that lung and large intestine are exterior and interior.
