The cardiovascular system plays a vital role in maintaining the body's overall function by facilitating the transportation of essential nutrients and waste products. This system consists of the heart, blood vessels, and blood, working together to deliver oxygen and nutrients to tissues while removing waste products such as carbon dioxide. Starting with the heart, this muscular organ serves as a pump that propels blood throughout the body via a network of blood vessels. The blood vessels, including arteries, veins, and capillaries, serve as conduits for blood flow, carrying oxygen-rich blood away from the heart to the body's tissues and returning oxygen-depleted blood back to the heart.
