  4. 11. A combination of the first and second onomatopoeia heart sounds which describe the closure of the AV Valves and the later closure of the semilunar valves
  5. 12. Sections of the heart that receive incoming blood
  6. 13. When blood flows back from where it left through the valve, moving in the opposite direction causing collisions with the blood moving in the correct direction
  7. 14. _______ volume is the volume of blood that is pumped out of the chamber after each contraction

  10. 18. When the volume in a chamber remains constant; our heart can be in this state during ventricular contraction or relaxation
  11. 23. What phase of action potential in contractile cardiac muscle cells prevents their fatigue?
  12. 24. The cardiac cycle has two types of alternating periods: one called systole which is emptying and contracting, the other is called ______ which is relaxing and filling
  13. 25. A type of stroke volume regulation controlled within the heart

  1. 1. An atypical heart sound that can be due to turbulent flow of blood through malfunctioning valves
  2. 3. A type of activity that can cause either heart rate or stroke volume to increase, resulting in an increased cardiac output
  3. 4. Which pacemaker potential component slows due to acetylcholine being released by the parasympathetic NS?
  4. 5. A type of valve that makes a whistling sound due to a stiff and narrow valve that doesn’t completely open
  5. 6. Chambers in the heart that pump blood away to either lungs or organ systems
