Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
The circulatory system helps to fight off disease, helps the body maintain a normal body temperature, and provides the right chemical balance to provide the body’s homeostasis, or state of balance among all its systems.
(The circulatory system consists of four major components):
The Heart: About the size of two adult hands held together, 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 heart where it is directed to the lungs to 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
