Across
- 4. nerve Releases noradrenaline to speed up heart rate
- 7. Sustained systolic BP > 140 mm Hg or diastolic BP > 90 mm Hg
- 8. viscosity A factor affecting vascular resistance
- 10. Important supplement to lower BP
- 12. resistance Resistance to blood flow in vessels
- 13. loss Non-pharmacological method to reduce BP
- 15. Substances that increase vessel diameter
Down
- 1. Lowest aortic pressure before ventricular ejection
- 2. Sum of vascular resistances in systemic circulation
- 3. oxide Local endothelial factor that reduces BP
- 5. Maximal aortic pressure during heart contraction
- 6. pressure Force the heart uses to pump blood
- 9. The strength of heart contractions
- 11. rate How often the heart beats
- 14. node Receives signals to regulate heart rate delay
