  • Cell Organisation and the Circulatory System
    • An organ system (like the circulatory system) is a group of different organs working together to perform a particular function.
    • The heart has four chambers and four major blood vessels.
    • Blood circulates in only one direction to keep the amount of blood cells seperate.
      • Valves prevent the backflow of blood
