Cardiovascular System and ECG
Across
- 5. Graphic representation of this activity
- 6. Heart Contraction
- 7. Heart Relaxation
- 8. Protective outer most layer of a blood vessel
- 11. volume of blood ejected by a ventricle with each heartbeat (normal equals 70mls per minutes)
- 13. normal heart sound, caused by closing of AV valve
- 14. works as body's thermostat
- 16. Starts at the beginning of ventricular depolarization to end of ventricular repolarization
- 17. State at which muscles are at rest and electrical charges are balanced
- 18. Slower heart rate <60bpm
- 20. Abnormal heart sounds, indicates valve problems
- 21. a temp >38°C (100.4°F)
- 22. Low blood pressure
- 27. Undefined wave with repolarization
- 28. Ventricular contraction (ventricular depolarization)
Down
- 1. Rapid, uncoordinated shuddering of the heart muscle
- 2. 1 complete heartbeat
- 3. Divides heart longitudinally
- 4. changes voltage into mechanical motion and recorded onto heat sensitive paper
- 5. Instrument used to record electrical activity of heart
- 6. Starts at the end of ventricular depolarization to the beginning of ventricular repolarization
- 9. without a fever
- 10. Lack of blood supply to heart
- 12. “Skeleton of the heart”
- 15. Friction reducing layer of a blood vessel, that provides a slick surface for blood to flow through lumen
- 19. Receiving chamber of the heart
- 23. Atrial contraction (atrial depolarization)
- 24. Rapid heart rate >100bpm
- 25. normal heart sound, caused by closing of semilunar valve
- 26. Smaller veins, drain capillaries
