in the systemic and pulmonary circulations.
The cardiovascular system is also called the blood vascular or circulatory system, consists of a muscular pumping device, the heart and a closed system of blood vessels called arteries, veins and capillaries. As the name implies, the blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through various circulations of the body. Blood is a viscous fluid composed of a liquid intercellular substance known as plasma and formed elements. The heart, blood and blood vessels work together to service the cells of the body. This organ system permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells.
