n. 1 (context physiology English) The parts of a animal body comprising the heart, veins, capillaries and arteries. 2 The parts of a machine responsible for the circulation of some fluid.
n. the organs and tissues involved in circulating blood and lymph through the body [syn: cardiovascular system]
The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. The study of the blood flow is called hemodynamics. The study of the properties of the blood flow is called hemorheology.
The circulatory system is often seen to comprise two separate systems: the cardiovascular system, which distributes blood, and the lymphatic system, which circulates lymph. The passage of lymph for example takes much longer than that of blood. Blood is a fluid consisting of plasma, red blood cells, white blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. Lymph is essentially recycled excess blood plasma after it has been filtered from the interstitial fluid (between cells) and returned to the lymphatic system. The cardiovascular (from Latin words meaning "heart" and "vessel") system comprises the blood, heart, and blood vessels. The lymph, lymph nodes, and lymph vessels form the lymphatic system, which returns filtered blood plasma from the interstitial fluid (between cells) as lymph.
While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The lymphatic system, on the other hand, is an open system providing an accessory route for excess interstitial fluid to be returned to the blood. The more primitive, diploblastic animal phyla lack circulatory systems.
Circulatory System is a psychedelic rock musical ensemble formed by musician/painter Will Cullen Hart, and featuring Derek Almstead, Suzanne Allison, Peter Erchick, John Fernandes, Charlie Johnston, and Heather McIntosh.
Hart, part of the Elephant Six Collective, was one of the lead players in The Olivia Tremor Control. After that group disbanded in 2000, he and most of the other former Olivias, with the exception of Bill Doss (who was focusing on his solo project Sunshine Fix), and Eric Harris, formed Circulatory System. Neutral Milk Hotel's Jeff Mangum also contributed to their albums, but was only briefly part of the touring version of the band.
Their third full-length album, Mosaics within Mosaics, was released on June 24, 2014.
Circulatory System is the first album by the American music ensemble Circulatory System. It was released on August 28, 2001, on frontman Will Cullen Hart's Cloud Recordings label.
Pitchfork Media named Circulatory System the fifth best album of 2001.
The album artwork is based on that of fellow Elephant 6 act The Olivia Tremor Control's debut album Music from the Unrealized Film Script, Dusk at Cubist Castle.
