Across
  1. 2. The name given to the collection of arterioles, capillaries the venules (Organization).
  2. 4. The abnormal heart sounds that happen from blood flowing through malfunctioning valves turbulently (Sounds).
  3. 6. What heart sound is known as dup and is high-pitched, sharp, relatively short, and associated with the semilunar valves? (Sounds).
  4. 11. Blood pressure reflexes monitor and regulate this type of arterial pressure (Pressure).
  5. 12. The blood vessels that are formed when capillaries join together (Organization).
  6. 14. The blood vessels that are formed by the merging of venules (Organization).
  7. 15. This pathway conducts pacemaker activity from the SA node to the AV node (Pathways).
  8. 17. Left or Right? What ventricular pressure swings between a low of 0 mm Hg during heart chamber refilling with blood to a high of 120 mm Hg during heart chamber contracting (Pressure)?
  9. 20. The blood vessels that branch from the arteries when they reach the organs they are supplying (Organization).
  10. 21. This node exhibits an autorhythmicity of 50 action potentials and is found at the base of the right atrium (Nodes).
  11. 23. The middle layer of the heart wall that is composed of cardiac muscle (Heart walls).
  12. 24. The blood vessels that are formed when arterioles branch (Organization).
  13. 27. This pressure drops dramatically across the length of the arterioles. This causes systolic to diastolic swings in pressure that are converted to a non-pulsatile pressure when blood flows through the arterioles (Pressure).
  14. 28. A structurally damaged valve that produces an abnormal swishing sound (Sounds).
Down
  1. 1. The thin layer of endothelial tissue that lines the inside of the heart chambers (Heart walls).
  2. 3. What heart sound is known as a lub and is low-pitched, soft, relatively long, and associated with the AV valve? (Sounds).
  3. 5. a device used to measure systolic and diastolic arterial blood pressure (Pressure).
  4. 7. The end volume of blood remaining in the ventricle when ejection is complete (Volumes).
  5. 8. This pressure is the difference between systolic pressure and diastolic pressure (Pressure).
  6. 9. This node exhibits 70 action potentials and is found in the wall of the right atrium (Nodes).
  7. 10. This pathway conducts pacemaker activity from the right atrium to the left atrium (Pathways).
  8. 13. What pressure fluctuates between a peak pressure of 80 mm Hg for heart chamber contracting and a low pressure of 80 mm Hg for heart chamber refilling with blood (Pressure)?
  9. 16. The end volume of blood in the ventricle when filling is complete (Volumes).
  10. 18. Blood vessels that act as a pressure reservoir and carry oxygenated blood away from the heart(Organization).
  11. 19. This is a thin membrane filled with pericardial fluid that covers the surface of the heart (Heart walls).
  12. 22. The volume of blood ejected/pumped out with each contraction (Volumes).
  13. 25. an autoimmune disease triggered by streptococcal bacteria. It has the word fever at the end (Sounds).
  14. 26. A stiff narrow valve that produces an abnormal whistling sound (Sounds).
