Presentation transcript:

Renaissance Man #3 – 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.

What did Harvey prove? Harvey showed that blood returns to the heart from the body via veins. It is then pumped to the lungs. Blood carrying oxygen flows from the lungs to the heart. Blood leaves the heart to circulate round the body via arteries.

Harvey’s methods Harvey’s methods included: 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.

The impact of Harvey’s work 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?
