Abstract: A new human body’s structure was introduced, which can not only show the harmony between the human body and the natural world, but also discover the mechanism of life, health and disease quantitatively. Based on the nurturing and restricting relationships between the Five Zangs in Chinese medicine, a mathematical model was founded. According to the statistical data of the human body’s metabolism, numerical simulation on the seasonal variation of the energizing nutrients and energy flow of the Five Zangs that was stated by Chinese medicine traditionally had been done in this paper. The simulated results were compared with the seasonal climatic variation in China. The wave crests of the energizing nutrients of Pi, Fei, Shen, Gan and Xin are in July, October, January, April and July in this given order. The wave crests of their energy flow are delayed by 1/4 years to that of the energizing nutrients. On the phase plane that consisted of the energizing nutrients and energy flow of the Five Zangs, the locus repeats again and again but not in the same manner. The human body’s structure stated by Chinese medicine is the nurturing and restricting relationship structure through the media of energizing nutrients and energy flow. The relationship structure let the variation of the energizing nutrients and energy flow of the Five Zangs has the same dynamical features with the seasonal climatic variation in China. The quantitative measurement on the energizing nutrients and energy flow may be a complete new approach to discover the mechanism of life, health and disease.
