Across
- 3. Recoil of elastic arteries keeps blood flowing during ventricular relaxation
- 6. the flow of blood from a metarteriole through capillaries and into a postcapillary venule
- 10. a very small vein, especially one collecting blood from the capillaries.
- 13. plasma membranes of endothelial cells form a continuous tube that is interrupted only by intercellular clefts, gaps between neighboring endothelial cells
- 17. the development of new blood vessels
- 19. it is made up of one layer of endothelial cells
- 21. it lies between the tunica intima on the inside and the tunica externa on the outside.
- 22. monitors the blood flow into the capillary
- 23. the inside space of a tubular structure such as an artery or intestine
- 24. a network of 10-100 capillaries that arises from a single metarteriole
- 26. helps regulate blood pressure in the brain
- 29. the dilatation of blood vessels, which decreases blood pressure
- 30. the outermost layer of a blood vessel, surrounding the tunica media
Down
- 1. a network of small blood vessels that supply the walls of large blood vessels
- 2. Distribution of blood to each of the various organs
- 4. venule that receives blood from a capillary
- 5. any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart
- 7. the proximal end of a metarteriole i surrounded by scattered smooth muscle fibers whose contraction and relaxation help regulate blood flow
- 8. the alternative route of the blood flow to a body part through an anastomosis
- 9. The terminal end of the arteriole, this region tapers toward the capillary junction
- 11. a small branch of an artery leading into capillaries
- 12. the opposition of blood flow
- 14. a layer of elastic tissue that forms the outermost part of the tunica intima of blood vessels
- 15. an artery with a large number of collagen and elastin filaments in the tunica media, which gives it ability to stretch in response to each pulse.
- 16. Arteries that do not anastomose
- 18. any of the muscular walled tubes forming part of the circulation system by which blood is conveyed from the heart to all parts of the body.
- 20. intermittent contraction and relaxation, which may occur 5-10 times per minute
- 25. the constriction of blood vessels, which increases blood pressure
- 27. arteries Medium sized arteries
- 28. The union of the branches of two or more arteries supplying the same body region
