Across
  1. 3. white blood cells
  2. 4. smallest arteries; control flow into capillary beds via vasodilation and constriction
  3. 8. reversibly binds with oxygen
  4. 9. thrombus found in blood
  5. 10. carry blood away from the heart
  6. 11. smallest blood vessels
  7. 12. generates impulses about 75 times/minute
  8. 13. Lead the body’s counterattack against parasitic worms and lessen the severity of allergies by phagocytizing immune complexes
  9. 15. relaxation of heart muscle
  10. 17. blood has abnormally low oxygen-carrying capacity
  11. 18. Are formed when capillary beds unite
  12. 19. fragments of megakaryocytes
  13. 20. Thick-walled arteries near the heart; the aorta and its major branches
  14. 23. condition where the number of circulating platelets is deficient
  15. 25. our body’s bacterial slayers
  16. 28. Sustained elevated arterial pressure of 140/90 or higher
  17. 30. carry blood toward the heart
  18. 31. This defect causes RBCs to become sickle-shaped in low oxygen situations
Down
  1. 1. They are the largest leukocytes
  2. 2. carry the impulse to the heart apex and ventricular walls
  3. 5. heart rate over 100 beats/min
  4. 6. Force per unit area exerted on the wall of a blood vessel by its contained blood
  5. 7. distal to elastic arteries; deliver blood to body organs and are active in vasoconstriction
  6. 13. the number remains constant and reflects a balance between RBC production
  7. 14. contraction of heart muscle
  8. 16. red blood cells
  9. 21. heart rate less than 60 beats/min
  10. 22. Have large granules that contain histamine an inflammatory chemical that acts as a vasodilator and attracts other WBCs
  11. 24. cancerous conditions involving white blood cells
  12. 26. low BP in which systolic pressure is below 100 mm Hg
  13. 27. Found mostly in lymphoid tissue (some circulate in the blood)
  14. 29. contains over 100 solutes
