Circulatory system and brain. Computer artwork showing the blood vessels (blue and red) and bones (transparent) of the head and neck. Also seen is the brain (pink) and teeth (lower left). The cardiovascular, or circulatory system, transports oxygen and nutrients to all cells and tissues in the body via the blood. Its major components are the heart (not seen), the veins (blue), the arteries (red) and the blood that flows within them.
