The relationship between the five viscera and six bowels of the heart and small intestine, lungs and large intestine, liver and gallbladder, kidney and bladder, spleen and stomach for each other. 1. The heart and the small intestine with each other is explained from the meridian genus, the heart meridian is the heart of the small intestine, small intestine meridian is the small intestine with the heart. Physiological correlation between the two, the blood of the heart descending through the small intestine, small intestines, absorption of water and grain micro-essence, through the spleen to the heart, blood moistening the heart veins. 2. The lungs and the large intestine are related to each other in physiology and pathology. Physiologically, the descent of lung qi and the dispersal of fluid can promote the conduction function of the large intestine and facilitate the discharge of dross. Conversely, smooth conduction in the large intestine is also conducive to the purging and descending of lung qi. Pathologically, poor conduction in the large intestine affects the lungs, resulting in wheezing, coughing and chest fullness (chest distension and discomfort). 3. Physiologically, the spleen and stomach are connected by membranes, and they are connected to each other through the meridians, forming a relationship of mutual cooperation. They work closely together to accomplish digestion and absorption of food and drink. 4. Liver and gallbladder, physiologically gallbladder dependent on the liver, due to the meridians, they constitute the relationship between the two, the liver is the main planning, gallbladder is the main decision-making, the two are used for each other. 5. Kidney and bladder, the two have meridians and veins, so for the relationship between the two, the relationship is mainly reflected in the water metabolism. If the above organs are in discomfort, it is recommended to consult a doctor in a timely manner, under the guidance of the doctor for scientific treatment.
