Observation and experimentation
It circulates continuously
Blood is created in the liver and burnt up
Studying the slow beating hearts of cold blooded animals
Blood could only go round one way
the heart was in the centre of the body
it was impossible for the body to have too much blood
On the motion of the heart
people wouldnt acsept it because it contradicts galens theories and took 50 years for the university of paris to teach them
Couldnt explain why blood circulated the body or why it would change colour in veins and arteries
