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, 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 to describe venous valves. In 1628, William Harvey published his description of blood circulation in De motu cordis. This term is opposed and contrasted to the term pulmonary circulation first proposed by Ibn al-Nafis.
