Circulatory system: the organs and tissues involved in circulating blood and lymph through the body
Source: WordNet 2.1
As most of the cells in the human body are not in direct contact with the external environment, the circulatory system acts as a transport system for these cells. Two distinct fluids move through the circulatory system: blood and lymph.
Your heart and blood vessels make up your circulatory (SIR-kyoo-la-TOR-ee) system. Your heart is a big muscle that pumps blood through your body. Your heart pumps blood carrying oxygen to large blood vessels, called arteries (AR-ter-eez), and small blood vessels, called capillaries (KAP-ih-lair-eez). Other blood vessels, called veins, carry blood back to the heart. (Source: excerpt from Keep your heart and blood vessels healthy: NIDDK)
Circulatory system: The circulatory system includes the organs, structures and substances of the heart and blood vessels. The circulatory system is responsible for a variety of functions throughout the body. This includes pumping and transporting blood, which carries vital oxygen and nutrients to the body's cells. The blood cells of the circulatory system also provide clotting and infection fighting mechanisms for the body. The circulatory system interacts and works together with every other system in the body, including the nervous system, genitourinary system, musculoskeletal system, immune system, respiratory system, digestive system and endocrine system.
