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