Brief introduction to nouns:
The heart is one of the five internal organs, located above the chest diaphragm and between the lungs, and protected by the pericardium. Through rough dissection, the ancients described the shape of the heart as a drooping lotus. The shape of the heart observed and described by the ancients is the same organ as the heart of modern medicine.
The main physiological function of the heart is to control blood vessels and store spirit. The veins in the body are combined, the flowers are on the face, and the tongue is enlightened. In the mind, it is happy, in the liquid, it is sweat. The meridians of the heart are connected with the small intestine and form exterior and interior with the small intestine. The heart belongs to fire in the five elements, located in the chest, is the yang in the yang, and is connected with summer qi.
Traditional Chinese medicine believes that the main physiological function of the heart is to promote blood circulation and carry out mental thinking activities, which plays a leading role in human life activities. It is an important zang-fu organ, so when the ancients explained medicine with social phenomena, they used monarch, minister, general and phase to simulate its function and were satisfied with "the official of the monarch". "Lingshu Evil Guest" yue; "The heart is the master of the five internal organs, and the spirit is also given up."
Internal structure of the heart:
The hollow organ mainly composed of myocardium has four cavities: left atrium, left ventricle, right atrium and right ventricle. The left ventricle is connected to the aorta, the right ventricle to the pulmonary artery, the left atrium to the pulmonary vein, and the right atrium to the superior and inferior vena cava.
The left and right atria and the left and right ventricles are separated by a diaphragm, so they are not connected to each other. There is a valve between the atrium and the ventricle, so that blood can only flow from the atrium into the ventricle, but not back.
The relationship between five internal organs and six internal organs;
Viscera refers to various organs in the human body. "Viscera" refers to solid organs, including heart, liver, spleen, lung and kidney, and fu-organs refer to hollow containers of five fu-organs corresponding to five internal organs, such as small intestine, gallbladder, stomach, large intestine and bladder. In addition, the thoracic cavity and abdominal cavity of human body are divided into upper coke, middle coke and lower coke.
Zang-fu organs and fu-fu organs cooperate with each other from the outside to the inside, with one zang-fu organ corresponding to one fu-fu organ, the zang-fu organ belonging to yin as the inside and the fu-fu organ belonging to yang as the outside. The exterior and interior of zang-fu organs are connected by meridians, that is, the meridians of zang-fu organs and fu-fu organs are connected by meridians and qi, so zang-fu organs and fu-fu organs can influence and change each other in pathological changes.
