William Harvey - The Heart

Extracts from this document...

Introduction

William Harvey -The Heart William Harvey was born April 1, 1578, Folkestone, Kent, England and died in June 3, 1657, London. William Harvey was an English physician and discoverer of the true nature of the circulation of the blood and of the function of the heart as a pump. Functional knowledge of the heart and the circulation had remained almost at a standstill ever since the time of the Greco-Roman physician Galen - 1,400 years earlier. He studied medicine and later became a lecturer in anatomy. He was determined to find out or discover a breakthrough about how the heart and blood worked in the body. ...read more.

Middle

Harvey wasn't too sure of this and begun to suspect that, that was not what happens, and that the blood does not get used up. From dissecting many creatures, including humans, English physician William Harvey discovered the nature of blood circulation and the function of the heart as a pump. Before his discoveries blood was thought to ebb and flow through the body by the contraction of arteries. Harvey's work also laid down the foundations of physiology, the study of body functions. William Harvey was positive that this was not true as he had seen lots of humans and animals dissections and he thought that that was not possible. ...read more.

Conclusion

Despite this he still kept at it and later on produced another book about animals. Now he was well known and was now recognised as a 'Medical Leader' and was appointed doctor for King Charles I. William Harvey's discovery was very good. He would not have made the discovery without his great determination. Even when the odds were against him he still had hope and eventually got there in the end. Without his discovery we wouldn't know a lot of things about the heart and circulation of the blood as all the following people followed up on his research and discovered new things about it; Malpighi -- Saw capillaries in the lungs, S. Hales -- Measured blood pressure, Landsteiner -- Blood groups worked out and Perutz who discovered haemoglobin. ...read more.
