The impact of Vesalius…
Vesalius showed that some of Galen’s ideas were wrong. Many doctors
refused to believe him, but his work did encourage doctors to question
ancient ideas rather than just accept them.
In the long-term, Vesalius’s work on anatomy was of huge importance
and helped doctors make new discoveries about the way the body
worked.
What impact do you think Vesalius had on ordinary people’s lives?
How much of a difference did he make to the development of medicine?

Take Notes
• Who was William Harvey and what did he do?
• Add to your notes from the Textbook.
• What did he do, how did he do it, what was the impact of his work.

William Harvey
William Harvey was an English doctor who discovered how the heart
worked and how blood circulated around the body.
Before Harvey, doctors had learnt from Galen that the body used blood like a
fuel. He had written that the liver continually produced blood to replace that
which the body had burnt up.
Harvey’s discoveries included that:
the heart works like a pump
blood flows in one direction only around the body
one-way valves stop the blood going the wrong way
blood is re-circulated and not replaced.

Harvey ‘s Methods
Dissecting live, cold-blooded animals. Their very slow heartbeat
allowed him to observe the actions of the heart. He also gained a
good knowledge of the human body through dissection.
Carrying out hundreds of painstaking experiments.
Carefully recording all his findings so that he could prove why he
was right.
Calculating the total volume of blood by measuring the amount of
blood pumped by each heartbeat.
Experimenting with rods in the veins. He found he could only
push them through the valves one way.

Impact of Harvey
Harvey couldn’t see the tiny capillaries which carry blood, though he knew
they must exist. With the invention of the microscope in the 17th century,
Harvey was proved right.
Like Vesalius three-quarters of a century before him, Harvey had dared to
challenge Galen and the other ancient writers. Many doctors again regarded
these new ideas as dangerous and carried on with their own methods.
However, Harvey’s discoveries were vital to the understanding of the way
the body works we have today.
What impact do you think Harvey had on ordinary people’s lives?
How much of a difference did he make to the development of medicine?
