In traditional Chinese medicine theory, essence, qi, and body fluids are important substances in the human body, and there is a close relationship between them and the functions of the body's five senses and organs.
Firstly, semen, qi, and fluid are important components in the human body, which are necessary for maintaining normal physiological functions. Among them, essence refers to the sum of innate and acquired essence stored in the kidney, which has the function of nourishing and moistening internal organs. Qi refers to the energy substances flowing within the human body, which have the function of promoting and warming the internal organs. Body fluid refers to the collective term for water and nutrients in the human body, which has the function of nourishing and nourishing the internal organs.
Secondly, there is also a close relationship between the five senses of the limbs and the functions of the organs. Traditional Chinese medicine believes that tissues such as the four limbs and bones, as well as skin, flesh, muscles, and bones, are dominated and controlled by internal organs. For example, the liver governs the contraction and relaxation of muscles and veins throughout the body; The spleen governs the muscles and can promote muscle growth and development; The lungs control the skin and fur, which can regulate the metabolism of human fluids and the patency of the respiratory tract. In addition, the five senses are also closely related to the functions of the organs. For example, the eye is the liver opening, which can reflect the health status of the liver; The tongue is the opening of the heart, which can reflect the health status of the heart; Ears are the orifices of the kidneys, which can reflect the health status of the kidneys.
在中医理论中，精气津液是人体内的重要物质，它们与肢体五官和脏腑功能之间存在着密切的关系。

首先，精气津液是人体内的重要成分，它们是维持人体正常生理功能所必需的。其中，精是指肾中所藏的先天之精和后天之精的总和，它具有滋养和濡润脏腑器官的作用。气是指人体内流动着的能量物质，具有推动和温煦脏腑器官的作用。津液是指人体内水液和营养物质的统称，具有滋润和濡养脏腑器官的作用。

其次，肢体五官与脏腑功能之间也有着密切的关系。中医认为，四肢百骸、皮肉筋骨等组织都是由脏腑器官所主宰和支配的。例如，肝主筋脉，支配着全身筋脉的收缩和舒张；脾主肌肉，可以促进肌肉的生长和发育；肺主皮毛，可以调节人体水液的代谢和呼吸道的通畅。此外，五官也与脏腑功能有着密切的关系，例如，目为肝之窍，可以反映肝脏的健康状况；舌为心之窍，可以反映心脏的健康状况；耳为肾之窍，可以反映肾脏的健康状况。
