circulatoire
Circulatoire is the term describing the circulatory system, the organ system responsible for moving blood through the body. It consists of the heart, a closed network of blood vessels—arteries, veins, and capillaries—and the blood that travels within them. A principal function is to deliver oxygen and nutrients to tissues and to remove carbon dioxide and other wastes. The system supports three integrated circuits: the pulmonary circuit, which sends deoxygenated blood from the right heart to the lungs for gas exchange; the systemic circuit, which distributes oxygenated blood from the left heart to the body; and the coronary circulation, which supplies the heart muscle itself. Lymphatic vessels and lymphoid tissues are related components that help return excess interstitial fluid to the circulation.
The heart acts as a muscular pump, with chambers and valves ensuring unidirectional flow. Blood pressure, cardiac
Regulation occurs via the autonomic nervous system, hormonal signals, and local factors that respond to tissue
Historically, William Harvey described systemic circulation in the 17th century, establishing a foundation for modern physiology.
