All cells in the body require oxygen, nourishment, and waste removal. The circulatory system performs these vital functions. The heart, blood, and blood vessels operate in tandem to provide service to the body. The network of arteries, veins, and capillaries transports carbon dioxide into the lungs and collects oxygen. Furthermore, the blood transports food nutrients from the small intestine to all cells.
– Arteries carry oxygen-rich blood from the heart to the rest of the body.
– Veins transport deoxygenated blood from the body to the heart.
– The Vena Cava is a large vein that delivers blood from other body parts to the heart. The vena cava has two parts: the superior vena cava, which transports blood from the head, neck, arms, and chest, and the inferior vena cava, which transports blood from the legs, foot, and abdominal and pelvic organs.
