The circulatory system, primarily consisting of the heart, blood, and blood vessels, carries materials throughout the body. Blood transports essential substances such as oxygen, nutrients, hormones, and waste products to and from cells. The heart pumps the blood, while arteries, veins, and capillaries facilitate its movement and exchange of materials. This system is crucial for maintaining homeostasis and supporting cellular functions.
