Presentation Transcript

  1. HISTOLOGY OF THE VESSELS Dr. Altdorfer

  2. HISTOLOGY OF THE VESSELS 1) Bloodvessels 2) Lymphvessels

  3. Definitions: 1) Artery: 2) Vein:

  4. ?

  5. Arteries - higher pressure  thicker walls, smaller lumen than accompanying veins.  Three concentric layers: tunica intima - tunica media -tunica adventitia (capillaries) (arteries!) (veins!)

  6. +Vasa vasorum, nerves (max. 5

  7. +Vasa vasorum, nerves (max. 5 +Vasa vasorum, nerves

  8. Elastic arteries Muscular arteries Arterioles Capillaries Venules Medium-sized veins Large veins

  9. Elastic arteries Muscular arteries Arterioles Capillaries Venules Medium-sized veins Large veins Windkessel function

  10. + vasa vasorum

  11. Atherosclerotioc plaque with haemorrhage

  12. Elastic arteries Muscular arteries Arterioles Capillaries Venules Medium-sized veins Large veins

  13. +Vasa vasorum, nerves (max. 5

  14. Medium sized vessels V A A V

  15. End arteries

  16. Elastic arteries Muscular arteries Arterioles Capillaries Venules Medium-sized veins Large veins Resistance vessels, sphincter vessels

  17. +Vasa vasorum, nerves (max. 5

  18. Arteriole

  19. Precapillary arteriole

  20. Elastic arteries Muscular arteries Arterioles Capillaries Venules Medium-sized veins Large veins Exchange vessels

  21. +Vasa vasorum, nerves (max. 5

  22. Capillary functions: exchange (diffusion; pinocytosis - transcytosis)secretion -endothelin – 1.-nitric oxide (NO = EDRF)-conn. tissue elements, etc.

  23. e.g. in muscles Fluid exchange e.g.: small intestine (resorption), endokrine glands, kidney Sinusoid: wide lumen Liver, spleen, endokrineglands, lymphnode Hepaticsinusoid liver

  24. Preferentialvessels

  25. Barriers: Blood-brain barrier (BBB)

  26. Elastic arteries Muscular arteries Arterioles Capillaries Venules Medium-sized veins Large veins in the adventitia: vasa vasorum! Capacitance vessels

  27. +Vasa vasorum, nerves (max. 5 +Vasa vasorum, nerves

  28. Postcapillary venules

  29. Venulen

  30. Medium sized vessels Medium-sized vein Medium-sized artery Muscular vein

  31. Valves in the veins Endothel-duplications Valve Skeletal muscle pump • Thrombosis, embolism, infarction • Thrombophlebitis • Cardiac bypass graft operation

  32. Large vein

  33. Special blood vesselsglomerulus – portal veins

  34. Receptors: carotid body (glomus) and sinus

  35. 1) Bloodvessels 2) Lymphvessels
