[Role of hypothesis in the formation and development of blood circulation theory].

ABSTRACT

The presentation of the theory of blood circulation saw an epoch-making significance in the history of Western medicine, and ushered medicine to the road of scientific development. From the early Galen's hypothesis of "septal pores" and the tidal motion of blood, which was questioned, followed by the discovery of the venous valve and pulmonary circulation successively through the studies by the scientists with great concentration. Until 1628, Harvey proposed the theory of blood circulation, followed by Malpighi's discovery of the capillaries, corroborating Harvey's "mysterious organization" hypothesis to form a perfect theory. Thus, the discovery of the theory of blood circulation is a process which is a necessary path for the formation and development of the theory of blood circulation and is also a process of repeated offering of hypotheses and its verification.
