Anatomy is the elemental knowledge of traditional Chinese medicine. The Yellow Emperor's Internal Classic contains numerous records regarding the dissection of the human body especially the blood circulation system. It not only describes the formation,
nature and function of the blood, but also explains the source which provides the blood ability to circulate and the hearts ability to pump that blood. Discussed are the organs to which the blood traveAnatomicalls, and the rate at which it is pumped.

In addition, the size, length, volume, and weight, as well as the shape, and linear measurements of some of the viscera are also recorded in the Classic on Medical Problems. During the Qing dy-nasty, Dr. Wang Qingren wrote the Correction of Medical Classic. It was through the observation of human cadavers, and of their internal organs that Dr. Wang Qingren verified existing anatomical records of his predecessors, including more than 20 picture illus-trations. Despite a few errors, Dr. Wang's scientific attitude is highly commendable.

Owing to the limitation of the historical condition, as well as the level of science, ancient doctors acquired only a superficial knowledge of the structure of the body. Because they were limited to naked eye observation, doctors were confined to knowledge of only macro-structures, far less than the anatomical composition known today. Moreover, the influence of feudal ethics hindered the further development of the science of anatomy. Despite this, anatomical knowledge did play an integral role in the formation of the visceral manifestation theory, and laid a scientific foundation in morphology.
