  6. 9. pressure: occurs as the ventricles fill with blood just before they contract
  7. 12. occurs when fatty deposits build up on arterial walls
  8. 15. failure: results when the heart cannot pump blood efficiently
  9. 17. pressure: occurs when the ventricles contract and the blood is pushed out of the heart
Down
  1. 1. atrium: contracts forcing the blood to the right ventricle
  2. 2. occurs when blood pressure is higher which puts extra strain on the heart
  3. 5. two lower chambers of the heart that contract at the same time during a heart beat
  4. 7. pressure: the force of the blood on the walls of the blood vessels
  5. 10. blood vessel that carries blood back to the heart
  6. 11. occurs when material moves from an area where there is more substance to an area where there is less substance
  7. 12. transport: requires an imput of energy from the cell
  8. 13. microscopic blood vessls that connect arteries and veins
  9. 14. atrium: contracts and forces the blood into the left ventricle
  10. 16. two upper chambers of the heart that contact at the same time during a heart beat
