Science - The Circulatory System

  1. List the four components of blood
    Plasma

    Red blood cells

    White blood cells

    Platelets
  2. List the three types of blood vessels
    Arteries

    Veins

    Capillaries
  3. State the function of plasma
    To transport food around the body

    To keep the body at the correct temperature
  4. State the function of white blood cells
    To fight against disease
  5. State the function of platelets
    To clot the blood
  6. State the function of red blood cells
    To transport oxygen around the body
  7. Give the differences between arteries and veins
    Arteries carry blood away from the heart whereas veins carry blood to the heart

    Arteries have no valves but veins have valves

    Arteries have a thick wall and a small lumen whereas veins have a thin wall and a large lumen

    The blood pressure in arteries is high whereas in veins the blood pressure is low
  8. State the function of arteries
    To carry blood away from the heart
  9. State the function of capillaries
    They connect (link) arteries and veins
  10. State the function of veins
    To carry blood to the heart
  11. What are the upper chambers of the heart called?
    Atrium
  12. What are the lower chambers of the heart called?
    Ventricles
  13. What is the function of the vena cava?
    To carry deoxygenated blood (high in carbon dioxide) from the body to the heart
  14. What is the function of the pulmonary artery?
    To carry deoxygenated blood (high in carbon dioxide) from the heart to the lungs
  15. What is the function of the pulmonary vein?
    To carry oxygenated blood (high in oxygen) from the lungs to the heart
  16. What is the function of the aorta?
    It is the largest blood vessel in the body and carries oxygenated blood (rich in oxygen) from the heart to every organ of the body
  17. What are valves?
    The valves consists of flaps that open to let blood flow in one direction as it moves through the chambers of the heart

    Then the valve close to keep blood from flowing backwards into the chamber it just left
  18. Why is the wall of the left side of the heart thicker than the right side?
    Because it has to pump blood to every part of the body

  19. Correctly identify the part of the heart labelled A
    Vena Cava
  20. Correctly identify the part of the heart labelled B
    Right Atrium
  21. Correctly identify the part of the heart labelled C
    Right Ventricle
  22. Correctly identify the part of the heart labelled D
    Pulmonary Artery
  23. Correctly identify the part of the heart labelled E
    Aorta
  24. Correctly identify the part of the heart labelled F
    Pulmonary Vein
  25. Correctly identify the part of the heart labellled G
    Left Atrium

  26. Correctly identify the part of the heart labelled H
    Left Ventricle
  27. What is the normal body temperature of an adult?
    37 degrees celsius
  28. State the normal heartbeat rate (pulse rate) of humans
    70 beats per minute
