The circulatory system consists of three main components: the heart, blood vessels, and blood. The heart acts as a pump to circulate blood throughout the body, while blood vessels, including arteries, veins, and capillaries, transport blood to and from various tissues. Blood carries oxygen, nutrients, hormones, and waste products, playing a crucial role in maintaining homeostasis and supporting cellular function. Together, these components ensure efficient circulation and overall health.
