The cardiovascular system incorporates the heart blood vessels and lymphatic vessels. The main purpose is to maintain adequate 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, immune cells, cytokines and other chemical messengers that work at distant sites in the body.
