How did William Harvey discovered blood circulation?
He isolated parts of the heart; he ligated and divided arteries; he exerted pressure on veins on either side of the valves.
His observations of dissected hearts showed that the valves in the heart allowed blood to flow in only one direction..
Who determined the circulatory system of the lungs?
The Arab physician, Ibn al-Nafis, wrote the Commentary on Anatomy in Avicenna’s Canon in 1242 in which he provided the first known accurate description of pulmonary circulation as it is known today.
Why is 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.
What did William Harvey discover about the heart?
He also discovered that the heart’s four valves permitted flow of blood in one direction only: from the right ventricle to the lungs, back to the left ventricle, and from there to the aorta. William Harvey was born on 1 April 1578.
What was believed before William Harvey?
Prior to Harvey, it was believed there were two separate blood systems in the body. One carried purple, “nutritive” blood and used the veins to distribute nutrition from the liver to the rest of the body.

What was William Harvey’s impact on medicine?
In 1628, the English physician William Harvey announced a revolutionary theory stating that blood circulates repeatedly throughout the body. He relied on experimentation, comparative anatomy and calculation to arrive at his conclusions.
What discoveries did William Harvey make?
William Harvey made the momentous medical discovery that the flow of blood must be continuous and that its flow must be in one direction only. This discovery sealed his place in the history of medicine. William Harvey was born in 1578 in Folkestone, Kent.

Why William Harvey was important?
English physician William Harvey was the first to recognize the full circulation of the blood in the human body and to provide experiments and arguments to support this idea.
How did Harvey prove Galen wrong?
His strongest evidence was that it would be impossible for the body to replenish the amount of blood it would consume under Galen’s theories. He arrived at this conclusion by calculating the total volume of blood that moves through the body in an hour and showed that it was too high for the body to replenish.
What area of medicine did Harvey challenge?
This book marked the end of Galen’s influence on anatomy. Harvey’s findings led to doctors attempting blood transfusions, as they now realised blood lost from the body needed to be replaced.
When was the blood circulation discovered?
Hieronymus Fabricius 1537–1619 He discovered the valves in the veins. He noticed that the blood cannot move from the heart toward the periphery through the veins. William Harvey 1578–1657 Explained the complete process of circulation.
