西医学将人体功能分到10个解剖系统,中医学将人体功能分到五藏系统。基于中、西医学的研究对象都是活着的人体,通过建立两种分类方法给出的功能之间存在的匹配关系,确认五藏系统的组成、特有功能和解剖定位。脾藏系统的特有功能对应消化系统的功能,肝脏的止血功能,运动系统骨骼肌的动力作用;肺藏系统的特有功能对应呼吸系统的吸入氧、排出二氧化碳和发音功能,免疫系统的防御功能;肾藏系统的特有功能对应泌尿、生殖、内分泌、造血系统的功能,免疫系统的识别和清除衰亡或变异细胞功能,运动系统骨骼的支撑作用;肝藏系统的特有功能对应神经系统的产生和传入感觉信号,传出运动信号调节躯体和内脏运动;心藏系统的特有功能对应脑的识别感觉信号,产生意识、思维、情感等精神活动和循环系统的体内物质运输功能。
Western medicine classifies the functions of human body into 10 anatomical systems, while Chinese medicine classifies the functions into 5-zang systems. Because of Western medicine and Chinese medicine have the same study object, a living human body, there must be matching relationships between the functions that coming from the two kinds of classification. This paper founded the components, specific functions and anatomical locations of five-zang system. The specific functions of Pi system are corresponding to the functions of digestive system, hemostasia function of liver, and motive power of skeletal muscle. The special functions of Fei system include inhaling oxygen and eliminating carbon dioxide of the respiratory system, pronunciation, and defense function of the immune system. The specific functions of Shen system include the functions of the urinary system, reproductive system, endocrine system and hematopoietic system, discriminating and clearing away senile or variable cells of the immune system, and support function of skeleton of the motor system. The special functions of Gan system are corresponding to producing and transferring sensory signals, and transferring motor regulate signals to somatic and visceral movements of the nervous system. The special functions of Xin system include braing distinguishing different sensory signals, generating mental activities, such as consciousness, thoughts, emotions, and etc. , and substance transporting functions of the circulatory system.
