How did William Harvey disprove Galen?

After having gone through the motions and reviewing his data, Harvey came to a conclusion that debunked both Galen's passable septum and his blood-producing liver: It has been shown by reason and experiment that blood by the beat of the ventricles flows through the lungs and heart and is pumped to the whole body…

How Harvey was able to disprove Galen's theory?

His first clue that something was amiss with Galenic theory was a consideration of the volume of blood that is pumped with each heartbeat. He realized that the liver would have to create several times the body weight in blood every day if the blood was actually being consumed.

What is the theory of blood flow?

Blood Flow

Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. The rate, or velocity, of blood flow varies inversely with the total cross-sectional area of the blood vessels.

Why is the knowledge of blood circulation important?

Blood circulation is an essential bodily function since it supplies the body's vital organs with enough oxygen and nutrients needed to operate. Poor blood circulation can potentially harm the heart, kidneys, and brain, and it may even have fatal consequences if left untreated.
