D. Gregor Mendel
E. None of above

Check Answer

The correct answer is C) William Harvey.

The first discovery of how blood circulates in the human body is credited to William Harvey. He was an English physician and anatomist who lived in the early 17th century. In 1628, he published his landmark book “Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus” (Anatomical Exercise on the Motion of the Heart and Blood in Animals), in which he presented his theory of blood circulation.

He proposed that the heart acts as a pump, sending blood through a system of vessels to the body’s various organs and tissues. He described the role of the heart in pumping blood and the circulatory system, and how it works, including the role of the valves in the heart and the vessels, and how the blood travels through the body and how it return to the heart.

Harvey’s ideas were revolutionary for the time, as they contradicted the long-held belief that blood was created in the liver and consumed by the body’s tissues. His work laid the foundation for modern physiology and his discovery is considered as one of the major medical discoveries of the 17th century.
