De motu cordis


De motu cordis


Harvey's small book is usually considered the most important single medical work ever published. In this book, Harvey announced his discovery of the circulation of the blood, gave a clear description of the heart's action, and reported the experiments that provided proof for his assertions. He had performed these studies by himself over a period of several years on many classes of vertebrate and invertebrate animals, and he had become convinced of the truth of his conclusions several years before this book appeared.

The book goes on to describe vividly the heart's movement and function in detail, together with experimental evidence that was derived from the dissection of cold-blooded animals, in which the slow motions of the heart can be readily observed. The valves in the veins are correctly described and their function explained with the records of his classic centripetal-flow experiments. Two illustrations are provided, reproducing four figures of the veins in the forearm, from Fabricius. Harvey's clear reasoning from the observations and precise measurements made during his purposeful experiments supplied the key for advancing knowledge of physiology and was also a model for future scientific procedure.
