Across
  1. 3. circulation: oxygen-rich blood flows to all the organs and body tissue
  2. 6. two lower chambers of the heart that contract at the same time during a heart beat
  3. 10. occurs when fatty deposits build up on arterial walls
  4. 14. circulation: flow of blood through the heart to the lungs and back to the heart
  5. 17. atrium: contracts and forces the blood into the left ventricle
  6. 18. vessels: carry blood to every part of your body
  7. 19. two upper chambers of the heart that contact at the same time during a heart beat
Down
  1. 1. atrium: contracts forcing the blood to the right ventricle
  2. 2. pressure: occurs as the ventricles fill with blood just before they contract
  3. 4. failure: results when the heart cannot pump blood efficiently
  4. 5. occurs when blood pressure is higher which puts extra strain on the heart
  5. 7. blood vessel that carries blood back to the heart
  6. 8. circulation: flow of blood to and front eh tissues of the heart
  7. 9. occurs when material moves from an area where there is more substance to an area where there is less substance
  8. 10. transport: requires an input of energy from the cell
  9. 11. microscopic blood vessels that connect arteries and veins
  10. 12. a hollow muscular organ that pumps blood through the circulatory system
  11. 13. pressure: occurs when the ventricles contract and the blood is pushed out of the heart
  12. 15. pressure: the force of the blood on the walls of the blood vessels
  13. 16. blood vessels that carry blood away from the heart
