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