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