Most simply stated, the major function of the cardiovascular system is transportation. Instead of roads, railway tracks, and subways, the body’s delivery routes are its hollow blood vessels. Like a bustling factory, the body must have a transportation system to carry its various “cargoes” back and forth. Thus, some means of changing and “refreshing” these fluids is necessary to renew the nutrients and prevent pollution caused by the buildup of wastes. Only with the interstitial fluid in their immediate vicinity.

NEW! What, How & Why chapter previews introduce key examples of anatomy and physiology concepts that will be covered in the chapter. Although the pace of these exchanges slows during sleep, they must go on continuously: when they stop, we die. Night and day, minute after minute, our trillions of cells take up nutrients and excrete wastes. However, the cardiovascular system is much more than just the heart, and from a scientific and medical standpoint, it is important to understand why this system is so vital to life. The crucial importance of the heart has been recognized for ages. We have all felt our own heart “pound” from time to time when we are nervous. Hen most people hear the term cardiovascular system, they immediately think of the heart. Body organs fail to function properly, and then, once oxygen becomes depleted, they will die.
WHY If the cardiovascular system cannot perform its functions, wastes build up in tissues. Blood flow requires both the pumping action of the heart and changes in blood pressure. HoW The heart pumps blood throughout the body in blood vessels. WHAT The cardiovascular system delivers oxygen and nutrients to the body tissues and carries away wastes such as carbon dioxide via blood.
