Across
- 3. Cholinergic receptors in the heart
- 5. Decrease baroreceptor firing engages this branch of the autonomic nervous system
- 8. These types of arteries buffer the large pressures generated by the heart
- 9. Ventricular depolarization on an ECG
- 11. These fibers spread the impulse through the ventricular free walls
- 14. Small vessels that serve as the primary cite for gas and nutrient exchange
- 17. Force of blood exerted on walls of blood vessels
- 19. Do metabolites normally stimulate dilation or constriction?
- 20. Force that must be overcome to push blood through the circulation
- 22. Period of the cardiac cycle where the mitral valve closes and the
- 27. Under normal circumstances this hormone causes dilation through β2 adrenergic
- 28. Something that modulates heart rate can be said to modulate
- 29. This mechanism couples intrinsic neuron activity with blood flow
Down
- 1. These autonomic nerves are spread more diffusely throughout the heart
- 2. Cholinergic receptors in the autonomic ganglia
- 3. This mechanism couples metabolic activity with blood flow
- 4. These ensure one-way flow in veins
- 6. Time between atrial and ventricular depolarization
- 7. Atrial depolarization on an ECG
- 10. Frictional force of blood acting on the endothelium
- 12. Mechanoreceptors located in the aortic arch
- 13. Product of stroke volume and heart rate
- 15. valve has yet to open
- 16. Something that modulates cardiac contractility can be said to modulate
- 18. The difference between end diastolic and end systolic volume
- 21. Initial stretch of the heart prior to contraction
- 23. direct blood back to the heart
- 24. β1 adrenergic receptors are located in the
- 25. Most muscular heart chambers
- 26. direct blood away from the heart
