When was the human circulatory system first accurately described?
Quick Answer
It was accurately described in 1628, when William Harvey published his theory of blood circulation.
The Full Story
In 1628, English physician William Harvey published Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus, a landmark work explaining that blood circulates continuously through the body. He showed that the heart functions as a pump, rather than a source that constantly creates blood. This was a major break from older medical beliefs inherited from antiquity. Harvey’s work is considered one of the foundations of modern physiology.
