Which component of the body does the cardiovascular system comprise?

The cardiovascular system is primarily made up of the heart, arteries, and veins. The heart functions as the central pump, propelling blood throughout the body, while arteries carry oxygenated blood away from the heart to the tissues. Veins, on the other hand, return deoxygenated blood back to the heart. Together, these components work to deliver oxygen and nutrients to the cells and remove waste products, playing a critical role in maintaining the body's overall health and functioning.
