General features of the cardiovascular system

Abstract

The purpose of this chapter is to provide a general overview of the cardiovascular system, to serve as a quick reference on the underlying physiological composition of this system. The rapid transport of molecules over long distances between internal cells, the body surface, and/or various specialized tissues and organs is the primary function of the cardiovascular system. This body-wide transport system is composed of several major components: blood, blood vessels, the heart, and the lymphatic system. When functioning normally, this system adequately provides for the wide-ranging activities that a human can accomplish. Failure in any of these components can lead to grave consequence. Subsequent chapters will cover, in greater detail, the anatomical, physiological, and/or pathophysiological features of the cardiovascular system. © 2009 Humana Press.
