The Circulatory System
The main function of the Circulatory System is to pump blood throughout the body. There are five main organs in the Circulatory System. They are 1. The Heart, 2. the Arteries, 3. The Veins, 4. The Capillaries, and 5. the Blood. The Heart uumps blood and oxygen throughout the body. The arteries moves blood away from the Heart. The veins moves blood back to the Heart. Capillaries drop oxygen and nutrients in all of your cells and pick up CO2 and other waste. Blood moves oxygen, nutrients , CO2, and waste to and from the Heart, it also contains platelets which cause scabs to form.
