The Heart: The heart rests near the center of the chest. Thanks to consistent pumping, the heart keeps the circulatory system working at all times.
Arteries: Arteries carry
oxygen-rich blood away from the heart and where it needs to go.
Veins: Veins carry deoxygenated blood to the
lungs where they receive oxygen.
Blood: Blood is the transport
media of nearly everything within the body. It transports hormones, nutrients,
oxygen, antibodies, and other important things needed to keep the body healthy.
