    to contract
  5. what does diastole mean
    relaxation
  6. what are atrioventricular valves
    located btw the atria and ventricles
  7. what are semilunar valves
    located in ventricle n artery
  8. diff. btw arties, veins n capillaries?
    • -arteries carry blood away from heart n have thick walls
    • -veins carry blood to the heart n have think lumen
    • -capillaries branch off arteries n supp;y body with blood, membrane is 1 cell thick
  9. what are the components found in blood
    platelets, white blood cells, red blood cells, blood plasma
  10. what is a pulse?
    when the blood that is pumped expands the walls of the blood vessels
