Across
  1. 2. repolarization of ventricular fibers
  2. 3. "heart strings" that anchor to the cusps to the ventricular walls. They originate from the papillary muscles.
  3. 6. fragments of giant cells; help close breaks in blood vessels
  4. 8. universal donor
  5. 10. ventricle contraction felt in arteries
  6. 13. universal recipient
  7. 14. 2 upper chambers of the heart; receive blood returning to heart, have thin walls and flap-like auricles projecting from their exterior
  8. 15. (bicuspid) separates left atrium from left ventricle
  9. 18. divides the atria and ventricles on each side
  10. 19. inner lining of the heart
  11. 21. fibers in the ventricles that transmit impulses to the right and left ventricles, causing them to contract
  12. 22. (ECG or EKG) recording of the electrical changes that occur in the myocardium during a cardiac cycle
  13. 24. thick vessels adapted for carrying high pressure blood AWAY from heart
  14. 25. sends oxygenated blood to the tissues and removes wastes
  15. 28. separates the right atrium from the right ventricle
  16. 29. any molecule that triggers an immune response
  17. 30. Blood vessels thinner than arteries that carry blood back to the heart
  18. 31. red blood cells; Biconcave discs that contain hemoglobin, transports oxygen and carbon dioxide
  19. 32. Membrane surrounding the heart
Down
  1. 1. white blood cells that fight infection
  2. 4. hemolytic disease in the newborn (HDN) caused by a blood group (Rh factor) incompatibility between the mother and the fetus
  3. 5. muscles responsible for pulling the atrioventricular valves closed by means of the chordae tendineae
  4. 7. 2 lower chambers of the heart; pump blood to body
  5. 9. muscular, middle layer of the heart
  6. 11. occurs when the antibodies bind to the foreign antigens causing the foreign RBC's to clump together
  7. 12. site of nutrient, electrolyte, gas, and waste exchange; return blood to venules
  8. 16. a large red bone marrow cell from which platelets are derived
  9. 17. sends deoxygenated blood to the lungs
  10. 20. hollow, cone-shaped muscular pump
  11. 23. area between the lungs containing the heart, aorta, venae cavae, esophagus, and trachea
  12. 24. protein molecules produced in an immune response to an encounter with an antigen not found in the body's own cells
  13. 26. depolarization of atrial fibers that lead to atrial contraction
  14. 27. outermost layer made of connective tissue; houses capillaries, coronary arteries, cardiac veins
