The book "Anatomical discussion on the movement of the heart and blood in animals" was written by the English doctor and scientist William Harvey. In this work, Harvey presented discoveries and research that gave new insights into the process of blood circulation in the animal body. He proved that blood circulates in a closed system of arteries and veins, and the heart is the central organ that ensures the movement of blood. This book is one of the most important works in physiology and anatomy, which revealed new information about the work of the heart and circulatory system, and became an important step in the development of medical science.
