William Harvey - circulation

William Harvey, born in 1578, studied medicine at Cambridge and Padua, and worked as a doctor in London. He is renowned for his 1628 publication on the motion of the heart and blood in animals, which established the concept of blood circulation. Harvey demonstrated that blood circulates around the body with the heart acting as a pump, refuting Galen's theory that blood was continuously produced by the liver. He showed that blood is carried away from the heart in arteries and returns in veins.
