Across
  1. 2. vessels that help maintain blood pressure and flow in your body
  2. 5. prevents the av valves from everting during ventricle contractions
  3. 11. when net pressure is negative and the flow is going into capillaries
  4. 13. external tissue layer of the heart inside a membrane
  5. 16. middle layer and main layer of the heart walls
  6. 17. abnormal heart sounds
  7. 20. small fibers of specialized cells that help perform synchronized contractions
  8. 22. smallest vessels that are formed when arterioles branch
  9. 23. channel blood back to the heart
  10. 24. mechanism for maintaining fluid balance between the blood and extracellular space
  11. 25. record of electrical activity in the heart
Down
  1. 1. regulated by sympathetic and parasympathetic nervous system
  2. 3. amount of blood pumped out of the chamber with each individual contraction
  3. 4. when net pressure is positive consists of fluid removal
  4. 6. an autoimmune disease triggered by streptococcal bacteria that leads to stenosis
  5. 7. groups of specialized cardiac muscle cells
  6. 8. a thin layer of smooth tissue that lines the inside of the heart
  7. 9. represents ventricle depolarization
  8. 10. stiff and narrow valve that doesn't open completely
  9. 12. rhythmic electric activity of heart muscle
  10. 14. main artery in the body
  11. 15. channel blood away from the heart
  12. 18. protective sac around the heart
  13. 19. mechanoreceptor sensitive to changes in pressure and rely information to brain
  14. 20. represents av node delay
  15. 21. ensures one way flow of blood
