Across
- 2. Most important factor affecting vascular resistance in Poiseuille’s law
- 3. Maximum arterial pressure during ventricular contraction
- 5. Average arterial pressure during one cardiac cycle
- 10. Graphical recording of the electrical activity of the heart
- 12. Force exerted by blood on the walls of blood vessels
- 13. Opposition to blood flow caused by friction between blood and vessel wall
- 14. Fibers that rapidly distribute electrical impulses through ventricular muscle
- 16. Local regulation where increased tissue metabolism causes vasodilation
- 18. Muscular layer of the heart responsible for contraction
Down
- 1. Ability of blood vessels, especially veins, to store blood
- 3. Natural pacemaker of the heart
- 4. Smallest blood vessels where exchange of gases and nutrients occurs
- 6. Local vascular control where smooth muscle contracts when stretched
- 7. Major resistance vessels that regulate blood flow distribution
- 8. Condition where the heart cannot pump enough blood to meet body metabolic demand
- 9. Difference between systolic and diastolic blood pressure
- 11. Node that slows electrical impulse transmission before it reaches the ventricles
- 12. Electrical pathway connecting the AV node to the ventricular conduction system
- 15. Lowest arterial pressure during ventricular relaxation
- 17. Blood vessels that serve as the main blood reservoir in circulation
