	Development (Growth & change)	Other information
	He compared studies on animals and humans.He realized that he could observe living animal hearts in action and then his findings would apply to humans. Galen had thought blood was formed,carried to the tissues and then consumed.Harvey realized this was wrong.His logic for suggesting circulation was that too much blood was being pumped out of the heart for it to be continually formed and consumed so it must be going round and round. He also identifiefed the difference between arteries and veins,which built on the discoveries of ERASISTRATUS and he noticed that blood changes colour as it pases through the lungs	Harvey's work was important and a turning point in anatomy although it didn't really change surgery.Bleeding continued to be performed and blood transfusions were not successful until the discovery of blood groups in the 1900's.
