The cardiovascular system incorporates the heart and blood vessels. The main purpose is to maintain blood circulation and hence the distribution of nutrients to tissues and the delivery of metabolic wastes to excretory/urinary organs. The endocrine and immune systems also use the blood circulation as conduits for hormones and immune cells, respectively.
