Across
- 2. high blood pressure
- 4. pressure sensor located in aorta and neck/thoracic arteries
- 6. liquid portion of blood
- 8. releases histamine in response to infection
- 10. volume of blood pumped by each ventricle in one minute
- 13. spiral bundles of contractile cardiac muscle tissue
- 14. relaxation
- 18. type O blood
- 19. circulation that feeds heart cells
- 21. alternative routes for blood delivery
- 22. contraction
- 24. pumping chamber of the heart
- 25. EKG - ventricular repolarization
- 26. heart valves that prevent backflow into the ventricles
- 29. EKG - depolarization of ventricles, repolarization of atria
Down
- 1. hormonal stimulus for erythropoiesis
- 3. bacteria slayer
- 5. force exerted on wall of blood vessel by blood
- 7. pacemaker of the heart
- 9. rapid irregular heart contractions, useless for pumping blood
- 10. detect drop in blood pH which causes blood pressure to increase
- 11. EKG - depolarization of the sinoatrial node.
- 12. smallest arteries, control blood flow into capillary beds
- 15. abnormally fast heart rate (>100 beats/min)
- 16. red blood cell
- 17. diameter only allows one red blood cell through at a time
- 20. major blood plasma protein
- 23. right atrioventricular valve - three flaps
- 27. receiving chamber of the heart
- 28. long term renal control of blood pressure manipulates this aspect of blood
