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:
“We did not heed the sentries at the gate, nor did they us, and what under the sun they were placed there for, unless to hinder a free circulation of the air, was not apparent.”
—Henry David Thoreau (1817–1862)
