What are the main components of the circulatory system?

The main components of the circulatory system include the heart, blood vessels, and blood. The heart pumps blood throughout the body, supplying oxygen and nutrients to the tissues and organs. The blood vessels, including arteries, veins, and capillaries, act as a network that carries blood to and from the heart. Blood is composed of red blood cells, white blood cells, platelets, and plasma, which work together to transport nutrients, oxygen, hormones, and waste products throughout the body. These components work together to ensure proper circulation and maintain the body's overall health and function.
