Circulatory System - Anterior View. The circulatory system is responsible for transporting blood throughout the body. The circulatory system includes the heart, arteries, arterioles, capillaries, venules and veins. The system is responsible for delivering oxygen and nutrients to organs, tissues and cells of the body, and for removing carbon dioxide and other waste products. The heart is the central pump for the system.
The circulatory system is the network of elastic tubes that carries blood throughout the body. It includes the heart, lungs, arteries, arterioles (ar-TE're-olz) (small arteries), and capillaries (KAP'ih-laireez) (very tiny blood vessels). These blood vessels carry oxygen- and nutrient-rich blood to all parts of the body. The circulatory system also includes venules (VEN' yoolz) (small veins) and veins. These are the blood vessels that carry oxygen- and nutrient-depleted blood back to the heart and lungs. If all these vessels were laid end-to-end, they'd extend about 60,000 miles.
