Circulatory System 2
William Harvey and Dr. Daniel Hale both were important in the development of our knowledge of the circulatory system. Tracing how knowledge of the circulatory system developed where does the work of Galen fit. What other individuals have contributed to the scientific knowledge of the circulatory system.
Galen Came in 1628 and I don't know who else contributed in the scientific knowledge of the circulatory system
ReplyDeleteGalen determined that the heart was in the center of the body, and, in his own words, "it is the hearthstone of the body"
ReplyDeleteAla-al-din abu Al-Hassan Ali ibn Abi-Hazm al-Qarshi al-Dimashqi, known as Ibn al-Nafis, was an Arab physician who is mostly famous for being the first to describe the pulmonary circulation of the blood.
ReplyDeleteHe was born in 1213 in Damascus.

Galen said that the heart is in the middle of the body.
ReplyDeleteGalen, a Greek physician who lived in the second century AD., spent his lifetime in observation of the human body and its functioning. Galen believed and taught his students that there were two distinct types of blood. 'Nutritive blood' was thought to be made by the liver and carried through veins to the organs, where it was consumed. 'Vital blood' was thought to be made by the heart and pumped through arteries to carry the "vital spirits." Galen believed that the heart acted not to pump blood, but to suck it in from the veins. Galen also believed that blood flowed through the septum of the heart from one ventricle to the other through a system of tiny pores. He did not know that the blood left each ventricle through arteries. Site: http://biology.about.com/library/organs/blcircsystem.htm
ReplyDeleteGalen showed his work of the circulatory system in 1628. The other people that contributed is Andreas Vesalius who had published something by him or something I don't know.

ReplyDeleteGalen figured out the heart is in the middle of the body
ReplyDelete1628
and damascus contributed to the discovery
Galen dicovered the location of the heart in 1628
DeleteGalen had a theory about the circulatory system.
ReplyDeleteGalen was this greek guy that was a surgeon and a Physician that looked at veins when he found them when he was detecting things

Galen was A Roman Physician. He discovered the different types of bloof
ReplyDeleteGalen fits in to the William Harvy and Dr. Daniel Hale picture because of his discoveries that are centered around the circulatory system. some of his dicoveries were the location of the heart in 1628, his discovery of the different types of blood, and he showed that arteries carried blood, not air. this is Galen's connections with William Harvey and Dr. Daniel Hale.

Aaron nice post concise and covers the essentials of the question.
DeleteGalen too made a very important discovery regarding the circulatory system. He actually was one of the first do discover the difference between blood found in veins and blood found in arteries. Andreas Vesalius also made many contributions to the circulatory system. He actually discovered the mitral valve which explains blood flow.
