How did Harvey falsify Galen?
Harvey employed experiment and deductive logic to show that arteries and veins are functionally, if not structurally, connected in the lung and the peripheral tissues, and that blood circulates. The mechanical force of the heart replaced Galen’s elusive attractive powers.
What did William Harvey disprove of Galen?
Through this careful and detailed research, Harvey was able to disprove Galen’s theory that the body made new blood as it used up the old. He proved that the heart was a pump which forced the blood around the body through arteries and that the blood was returned to the heart through the veins.

What influenced Galen and Harvey’s work?
Finally, in their use of analogies to represent the cardiovascular system, Galen and Harvey may have been influenced by the technologies of their day. Galen was interested in comparisons with smith’s bellows. In contrast, Harvey was likely to have been informed by force pumps, which were common in his time.
