Systemic circulation is the part of the cardiovascular system which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart. This physiologic theory of circulation was first described by Amato Lusitano (João Rodrigues from Castelo Branco, 1511-1568), a Portuguese doctor working in Italy, in his work composed by seven volumes Curationum Medicinalium Centuriæ Septem 1st. edition in 1551. He was the first who describe venous valves. In 1628 William Harvey launches his De motu cordis.
This term is opposed and contrasted to the term pulmonary circulation first proposed by Ibn al-Nafis.
Famous quotes containing the word circulation:
“There is probably not more than one hundred dollars in cash in circulation today. That is, if you were to call in all the bills and silver and gold in the country at noon tomorrow and pile them on the table, you would find that you had just about one hundred dollars, with perhaps several Canadian pennies and a few peppermint Life Savers.”
—Robert Benchley (1889–1945)
