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