This article analyzes the relationship between the heart and blood vessels based on the body-Qi concept in Inner Canon of Yellow Emporor（黄帝内经）. The authors regard the heart and blood vessels as the anatomical entity structure

transformed and generated from the fire and Qi between heaven and earth. The heart is the storage of Taiyang and fire Qi. The relationship between the heart and blood vessels is the transformation

the generation and nutrition for blood vessels from Taiyang and fire Qi stored in the heart

which is the function of body and Qi. The"heart governing blood vessels"in the Inner Canon of Yellow Emporor had no meaning that the heart could promote the blood running in the channels and meridians

which is of great significance to the further study of the concept of human body and the visceral manifestation theory of the heart.
