Circulation generally means the orderly movement or flow of something through a system or area. Most commonly, it refers to the movement of blood through the body, driven by the pumping action of the heart, which delivers oxygen and nutrients to tissues and removes waste. Beyond blood flow, circulation can also mean the movement or distribution of air, water, money, goods, information, or even social activity from person to person or place to place.
