Across
  1. 5. regulates the flow of blood between the right ventricle and the pulmonary arteries
  2. 12. the innermost layer of the heart that lines all chambers and valves
  3. 14. the lower chamber of the heart that contains deoxygenated blood
  4. 15. receives deoxygenated blood from the rest of the body
  5. 17. The amount of blood pumped by each ventricle in ONE minute.
  6. 18. Tiny cell fragments (platelets) that are responsible for clotting damaged blood vessels to prevent blood loss.
  7. 21. the upper chamber of the heart that contains deoxygenated blood
  8. 23. Red blood cell responsible for transporting oxygen to the body's tissues.
  9. 26. The fluid matrix that makes up 55% of blood composition.
  10. 30. the movement of blood between the heart and the lungs
  11. 31. The amount of pressure exerted on the arteries during systole and diastole.
  12. 32. Large vessels that carry oxygenated blood AWAY from the heart.
  13. 33. Pressure exerted by the contraction of the heart muscle.
  14. 36. Small vessel that transports oxygenated blood into the capillary bed.
  15. 37. Specialized tissue that regulates the contraction of the ventricles.
Down
  1. 1. The number of times the heart beats per minute.
  2. 2. transports deoxygenated blood from right ventricle to lungs
  3. 3. White blood cells responsible for identifying and fighting infection.
  4. 4. receives deoxygenated blood from the cephalic and thoracic regions
  5. 6. transports oxygenated blood to the whole body
  6. 7. Type of leukocyte that contains lobe-shaped nuclei and contains visible granules.
  7. 8. the lower chamber of the heart that contains oxygenated blood
  8. 9. the muscular part of the heart
  9. 10. Type of leukocyte that has spherical or kidney-shaped nuclei, with no visible granules.
  10. 11. the movement of blood from the heart through blood vessels to the rest of the body and back to the heart
  11. 13. A drop in pressure due to the relaxation of the heart as it is filling with blood.
  12. 16. transports oxygenated blood from lungs to the left atrium
  13. 19. regulates the flow of blood between the right atrium and right ventricle
  14. 20. ECG wave(s) that occurs as atria repolarize, and ventricles depolarize causing a ventricular contraction.
  15. 22. Large vessel that transports deoxygenated blood back to the heart.
  16. 24. ECG wave(s) that appears when ventricles become repolarized, signaling the end of a heart beat.
  17. 25. ECG wave(s) that occurs when the AV node depolarizes both atria causing them to contract.
  18. 26. the sac that encloses the heart to provide moisture and protection.
  19. 27. Cardiac pacemaker that regulates the contraction of the atria.
  20. 28. Extensions of the AV node that are embedded in the ventricles.
  21. 29. Tiny vessel responsible for providing oxygen and nutrients to tissues, and taking CO2 and waste away from the tissues.
  22. 31. regulates the flow of blood between the left atrium and left ventricle
  23. 32. regulates the flow of blood between the left ventricle and the aorta
  24. 34. Small vessel that takes CO2 and waste away from the capillary bed.
  25. 35. the upper chamber of the heart that contains oxygenated blood
