Across
  1. 3. deprived of adequate oxygen
  2. 6. Part of your autonomic nervous system. Your fight or flight response. Can act to increase your heart rate (2)
  3. 8. Chest pain caused by a fleeting deficiency in blood delivery to the myocardium (2)
  4. 9. Located in the right atrial wall, this is the heart's pacemaker (2)
  5. 10. The endocardial conducting network. These directly excite ventricular myocardial cells. This network is more elaborate in the left ventricle as it is much larger than the right (2)
  6. 13. The contraction of the heart- blood forced from the chambers (1)
  7. 14. The amount of blood returning to the heart and distending its ventricles (2)
  8. 17. Receiving chamber of the heart. Receives oxygenated blood from the pulmonary circuit (2)
  9. 18. The right atrioventricular valve (AV) (2)
  10. 20. Short, low pressure circulation (2)
  11. 21. Part of your autonomic nervous system. Your rest and digest response. Can act to decrease your heart rate (2)
  12. 24. All events associated with blood flow through the heart during one complete heartbeat (2)
  13. 25. The relaxation of the heart- heart fills with blood (1)
  14. 27. Amount of blood remaining in the ventricles after contraction (3)
  15. 30. Also known as the bicuspid valve, it is the left atrioventricular valve (AV) (2)
  16. 31. A condition where arteries harden and narrow due to the formation and accumulation of fatty plaque (1)
  17. 32. Long, high-pressure, high-friction circuit (2)
  18. 33. The right and left vessels transports oxygenated blood from the lungs to the heart (2)
Down
  1. 1. Decreased blood supply
  2. 2. Amount of blood ejected by each ventricle/beat. It is calculated using the formula EDV (end diastolic volume)-ESV (end systolic volume) (2)
  3. 4. This circulation is the functional blood supply of the heart. It is the shortest circulation in the body (1)
  4. 5. Blood clot. Can partially or completely block the flow of blood in a blood vessel (1)
  5. 7. Amount of blood in the ventricles during diastole (3)
  6. 8. Located above the tricupid valve. Action potentials propagate more slowly here to allow the atria to respond and complete their contraction before the ventricles contract (2)
  7. 11. Receiving chamber of the heart. Receives deoxygenated blood returning to the heart from the circulation (2)
  8. 12. Also called the bundle of His. It provides the only electrical connection between the atria and ventricles (2)
  9. 15. Pumping chamber of the heart. Pumps blood into the pulmonary trunk which takes the blood to the lungs (2)
  10. 16. The amount of blood ejected by each ventricle/minute. This value is calculated by multiplying heart rate with stroke volume (2)
  11. 19. Is a graphic record of heart activity (1)
  12. 22. Semilunar valve (SL). Guards the base of the aorta and prevents the flow of blood back into left ventricle (2)
  13. 23. Commonly called a heart attack. Myocardial cells die due to a lack of oxygen (2)
  14. 26. Semilunar valve (SL).Guards the base of the pulmonary trunk and prevents the flow of blood back into the right ventricle (2)
  15. 28. Pumping chamber of the heart. Pumps blood into the aorta, the largest artery in the body (2)
  16. 29. "Muscle heart". Composed mainly of cardiac muscle and forms the bulk of the heart. It is the layer that contracts (1)
