circulatory system

the major system concerned with the movement of blood and lymph; it consists of the heart and blood vessels. The circulatory system transports to the tissues and organs of the body the oxygen, nutritive substances, immune substances, hormones and chemicals necessary for normal function and activities; it also carries away waste products and carbon dioxide. It helps to regulate body temperature and helps maintain normal water and electrolyte balance.

The rate of blood flow through the vessels depends upon several factors: force of the heartbeat, rate of the heartbeat, venous return and control of the arterioles and capillaries by chemical, neural and thermal stimuli.
