The heart is located in the chest, between the lungs, shaped like an upside-down unopened lotus seed, surrounded by pericardium. The heart governs the blood vessels and the mind. The five elements belong to fire, and the yang belongs to yang, which corresponds to the summer of the four seasons. The function of the heart in the body is combined with the pulse, its brilliance on the face, its enlightenment on the tongue, its joy in ambition and its sweat in the liquid are 1. Main pulse: including main blood and main pulse. The blood of the whole body runs in the pulse and is transported to the whole body by the heartbeat of the heart to play its nourishing role. Only when the heart is full, can the blood flow continuously in the pulse and nourish the whole body, and then there will be a rosy complexion and a gentle and powerful pulse. If the heart is guilty, the blood is deficient and the pulse is unfavorable, it will cause the qi and blood to run poorly, or the qi and blood are empty, the complexion is dull and the pulse is weak; Even qi and blood stasis, blood vessels blocked, dark complexion, blue lips and tongue. 2, the main heart: God has a broad sense and a narrow sense. God in a broad sense refers to the external expression of human life activities, while God in a narrow sense refers to human spiritual consciousness and thinking activities. The heart plays a leading role in human life activities and occupies a primary position in the functional activities of various zang-fu organs. All the five internal organs must be regulated by the commander-in-chief of the heart in order to carry out unified and coordinated normal life activities. The liver is located in the abdominal cavity, under the diaphragm and in the right abdomen. The liver governs catharsis and blood storage. The five elements belong to wood, which is the yang in the yin, and the liver corresponds to the spring of the four seasons. The main reinforcement of the liver, manifested in the claws, enlightens the eyes, tears the liver in body fluid for the purpose of anger, and has the function of regulating qi, which is manifested in the following aspects. (1) regulating qi: the movement of qi moving up and down in the body is called qi. The function of zang-fu organs and the movement of qi and blood depend on the smooth regulation of qi. The function of the liver is normal, the qi movement is smooth, and the function of the viscera is normal. Discomfort will occur when the liver loses its function of dispersing qi and qi is not smooth. If you are depressed, you will have chest pain and less abdominal pain; Headache, blushing, and even syncope due to blood stasis may occur when qi goes against. (2) Promoting spleen and stomach transport: spleen governs ascending, stomach governs descending, and normal excretion of liver is an important condition to maintain normal ascending and descending of spleen and stomach. If the liver can't drain water, there will be symptoms such as bloating, diarrhea, nausea and vomiting. (3) Emotional mediation: the activity of mental emotion depends on the operation of qi and blood, and the smooth flow of qi makes the spirit happy; Qi disorder can lead to depression. 2, the main storage of blood: refers to the liver has the function of storing blood and regulating blood volume. Liver storing blood means that the liver has the functions of storing blood, preventing bleeding and regulating blood volume, so it is called "the liver is a sea of blood". When the body is active or emotional, the liver will distribute the stored blood outward. If liver blood deficiency, blood does not support eyes, eyes will be dry, blurred vision, or night blindness; If blood does not nourish tendons, the limbs will be numb and the flexion and extension will be unfavorable; Women can see irregular menstruation and less menstrual flow. If the liver does not store blood, there will be vomiting blood, nosebleeds, menorrhagia and even metrorrhagia. The spleen is located in the upper abdominal cavity, under the diaphragm and connected with the stomach through the membrane. Spleen is the biochemical source of qi and blood, which is the main source of transporting and transforming blood, ascending the clear, and distributing the essence and micro-Shui Gu. The viscera of human body depends on the nourishment of spleen, so spleen is called the foundation of the day after tomorrow. The five elements belong to the earth, which is the most yin of the yin, and the spleen corresponds to the long summer of the four seasons. Spleen dominates muscles and limbs, which is manifested in lips and mouth opening, thinking in brain and spleen in body fluid. 1. Main transport: refers to the function of transforming Shui Gu into fine substances and transmitting them to various organs and tissues of the whole body. In fact, it is the digestion, absorption and transportation function of nutrients. It can be divided into Shui Gu and water. (1) Shui Gu refers to the digestion and absorption of food and drink by the spleen. The function of spleen transport and transformation is normal, which can provide sufficient nutrition for qi, blood and body fluid, and can make the whole body viscera and tissues get sufficient nutrition. On the other hand, if the spleen loses its health, the digestion and absorption function of the body will be abnormal, resulting in abdominal distension, loose stool, loss of appetite and even burnout, emaciation, deficiency of qi and blood and other pathological changes. (2) Water-dampness transport: refers to the absorption and transport of water and body fluid by the spleen, which regulates the metabolism of water and body fluid, that is, the spleen cooperates with organs such as lung, kidney, triple energizer and bladder to regulate and maintain the balance of water and body fluid metabolism. Spleen has a vigorous function of transporting and transforming water and dampness, which can not only make all tissues in the body fully wet body fluids, but also avoid excessive water and dampness and retention. On the other hand, if the function of spleen transporting water and dampness is abnormal, it will inevitably lead to water stagnation in the body and produce pathological products such as water and dampness, phlegm and even edema. 2, the main blood, blood control: refers to the spleen to produce blood, blood control. Spleen is the foundation of the day after tomorrow and the source of qi and blood biochemistry. Spleen transport Shui Gu subtle, which is the main material basis of blood production. If the spleen loses health and blood-producing substances, the blood will be deficient, and there will be signs of blood deficiency such as dizziness, pale face, mouth, lips and nails. The function of regulating blood of spleen is realized by the function of qi sucking blood. If the transport function of the spleen decreases and the source of metaplasia is insufficient, qi and blood will be deficient, while qi deficiency can not control blood, resulting in bleeding. Spleen loses health, bleeding caused by yang deficiency will not control blood, and blood will not return to meridians. The clinical manifestations are subcutaneous hemorrhage, hematochezia, hematuria and uterine bleeding. , especially in the lower part. 3. The principle of clearing away heat means that the function of the spleen is to absorb nutrients such as Shui Gu and input them into the heart, lungs and head, and then transform qi and blood through the functions of the heart and lungs, thus nourishing the whole body and keeping the position of human internal organs relatively constant. The increase of spleen is contrary to the decrease of gastric turbidity. The spleen should be healthy when rising, and the stomach should be harmonious when falling. The spleen qi dominates the ascending, and the stomach qi dominates the descending, completing the digestion, absorption and distribution of diet. The function of clearing spleen is normal, and nutrients such as Shui Gu essence can be absorbed and distributed normally. A rising temper can prevent entrails from sagging. If the temper is not clear, Shui Gu will not be able to run qi and blood, and there will be symptoms such as fatigue, dizziness and diarrhea. Depression of spleen qi (also known as depression of middle qi) shows that lung and heart live together on diaphragm, communicate with trachea, communicate with nose and directly communicate with the atmosphere of nature. Lung governs qi and regulates breathing; The Lord announced that he would surrender; Waterway; The white pulse in the five elements belongs to gold, which is the yin and dirty in the yang, corresponding to the autumn of the four seasons. The lung is combined with the skin in the body, its flowers are in the hair, it is enlightened in the nose, it is worried in the mind, and it is crying in the liquid. Among the five zang-organs and six fu-organs, the highest ranking is the function of the lung of the five zang-organs, which is 1, and the main qi, the main breathing: the main qi of the lung includes the main body qi and the main breathing qi. As far as the generation of qi is concerned, the clear qi inhaled by the lung and the essence of Shui Gu, that is, the spleen and stomach metaplasia, constitute the ancestral qi. At the same time, the rhythmic breathing movement of the lungs regulates the movement of the whole body's qi, making the gas exchange inside and outside the body unimpeded and ensuring the normal life activities. 2. Xuanjiangsan: Faxuan refers to the function of lung qi rising to the periphery, which can expel turbid qi in the body and disperse the body fluid and Shui Gu essence regulated by the spleen; If lung qi loses its function of declaring hair, it will cause dyspnea, chest tightness, cough, anhidrosis and so on. Health refers to the function of the lungs to diffuse the inhaled natural clear air downward and keep the respiratory tract clean; If the lungs do not fall, there will be symptoms such as shortness of breath, wheezing and expectoration. 3. Water supply: It means that the lung can dredge and regulate the distribution, operation and excretion of water and liquid in the body through the function of declaring and descending. If the function of lung water channel is abnormal, water and liquid may stop gathering, and phlegm may produce drinks. 4, tidal white pulse: refers to the whole body blood will gather in the lungs, through the breathing of the lungs to exchange gas. The physiological function of the lung is to help the heart run blood. The beating of the heart is the basic power of blood circulation. The operation of blood depends on the promotion of qi, which moves to the whole body with the rise and fall of qi. If lung qi deficiency can't help the heart to circulate blood, it will affect the physiological function of the main blood vessels of the heart and cause blood circulation disorders, such as chest tightness, palpitation, cyanosis of the lips and tongue coating. The kidney is located at the waist, one left and one right, the lower right and the upper left, oval like cowpea. Kidney governs storing essence, growth and reproduction, water and qi. It is the source of yin and yang of human viscera and the source of life, so it is called the source of congenital. The five elements belong to water, which is the yang in the yin, corresponding to the four seasons in winter. The kidney governs the bone marrow, which is developing, opening the ears and yin, fearing ambition and spitting in the liquid kidney. Function 1, sperm storage, growth and reproduction: sperm storage means that the kidney has the function of storing essence and qi. Essence is the basic substance that constitutes the human body. The essence in a broad sense includes the living matter inherited from parents, that is, the innate essence, as well as the acquired essence that Shui Gu said. Although they come from different sources, both the innate essence and the acquired essence are hidden in the kidney. The innate essence prepares the material foundation for the acquired essence, and the acquired essence constantly supports the innate essence. The two complement each other and closely combine in the kidney to form essence hidden in the kidney. Kidney essence promotes reproduction, growth and development, participates in hematopoiesis and resists the invasion of external evils, which is also the material basis of various skill activities of human body. 2. Main water: broadly speaking, it means that the kidney is dirty with water, and generally it means that the kidney has the function of storing essence and regulating body fluid. In a narrow sense, it refers to the function of the kidney to preside over and regulate the metabolism of water and fluid in human body. The metabolism of water and liquid in human body includes two aspects: one is to transport body fluid with the function of nourishing and moistening viscera and tissues to the whole body in the subtle form of Shui Gu; The second is to excrete turbid liquid after metabolism and utilization of various viscera. Both of these aspects depend on the gasification of the kidney. The dysfunction of kidney in controlling water, poor gasification and disharmony in opening and closing will cause water-liquid metabolism disorder. Abnormal gasification, unfavorable door closing, and obstacles in urine production and excretion can cause pathological phenomena such as oliguria and edema; If you turn it on more and turn it off less, you can see symptoms such as polyuria and frequent urination. 3. Main Qi: It means that the kidney has the function of absorbing the gas inhaled by the lungs and regulating breathing. Kidney governs qi, which is of great significance to human respiratory movement. Only when the kidney qi is abundant and the intake is normal can the lungs breathe evenly and the airway be unobstructed. If the inspiratory function of the kidney decreases, it has no right to absorb, and the gas absorbed by people cannot be summarized in the kidney, so there will be pathological changes such as hyperventilation, difficulty in inspiratory and severe wheezing during exercise. Refers to the function that the kidney can absorb the air inhaled by the lungs and regulate breathing. Although breathing is mainly in the lungs, the gas inhaled by the lungs must be absorbed by the kidneys and used as a whole.
