The circulator system is an elaborate network made up of thousands of miles of veins, arteries and capillaries. Thanks to a steadily pumping heart, this system forces blood to every organ. The blood vessels not only deliver oxygen and nutrients to all parts of the body but also act as a transportation network for immune cells.
White blood cells in the form of lymphocytes, phagocytes, neutrophils and macrophages patrol the arteries in search of invaders. At any given moment, a trillion or more lymphocytes and other immune cells defend the body. Powered by the pumping heart, these cells flow through every branch of the circulatory network. Some flow freely in the bloodstream while others attach to vessel walls or pass into outlining tissues to fight harmful cells.
However, to function smoothly, the circulatory system must be well nourished to keep veins and arteries free of interfering substances such as cholesterol.
