Across
- 3. Disordered flow causing murmurs/bruits
- 5. Secondary routes for blood flow
- 6. Local adjustment of blood flow to tissue needs
- 9. Vessel response to pressure changes
- 11. Resistance in systemic circulation
- 12. Baroreceptor site in aortic arch
- 14. Tiny vessels supplying blood to vessel walls
- 16. Smooth, layered blood flow in vessels
- 17. Opposition to blood flow from friction
- 19. Blood flow through arterioles/capillaries/venules
- 20. Volume of blood moving through vessels per time
- 21. Smooth muscle regulating capillary blood flow
Down
- 1. Formation of new blood vessels
- 2. Sensors responding to chemical changes in blood
- 4. Pressure-sensitive feedback loop
- 7. Sympathetic nerves controlling vessel diameter
- 8. Baroreceptor site at carotid bifurcation
- 10. Thickness of blood affecting flow resistance
- 13. Alternate pathways between vessels
- 15. Increased vessel diameter via smooth muscle relaxation
- 18. Decreased vessel diameter via smooth muscle contraction
