  1. Slot 5. 26: Capillaries. Spread prepartion of mesentery and section of tendon • c = capillaries with RBC’s in single file • arrows = individual simple squamous epithelial cells Capillary Mast cell Arteriole

  2. Slot 5.27: Diagram of general structure of blood vessel

  3. Slot 5.28: Artery (l.s.) Tunica media (smooth muscle and elastic fibers) Lumen Tunica Intima Inner elastic membrane E=endothelial cells

  4. Slot 5. 29: Arterioles M=tunica media Red blood cells Tunica Intima Internal elastic membrane Endothelial lining Tunica media Tunica adventitia

  5. Slot 5.30: Vein (left) and Artery (right) Tunica intima Tunica media Tunica intima Tunica media Internal elastic membrane Simple squamous Tunica adventitia

  6. L=lymph capillary Arrows = endothelial cells Arrowhead=capillary Artery Muscle tissue Slot 5.31: Lymph capillary

  7. Slot 5.32: Lymph trunk—thoracic duct Tunica intima Tunica media Tunica adventitia Arrows = small blood vessels (vaso vasorum)

  8. Slot 5.33: Lymph node diagram

  9. Slot 5.34: Lymph node sections P = plasma cells Arrows = large lymphocytes Dashed line = germinal center -Lymph cells dispersed - Lighter staining S= Medullary sinus trabecula Cortex: note crowding of cells Medullary cord

  10. Slot 5.35: Palatine tonsil sections Arrows = arterioles Germinal centers C = mucosal crypt Germinal centers Simple squamous Lymph nodules

  11. Slot 5.36: Thymus T = thymic corpuscles = Hassall’s corpuscles Cortex Medulla Trabeculae divide into lobules

  12. Slot 5.37: Spleen diagram Lymph nodule = white pulp (surrounds central arteriole) Red pulp

  13. Slot 5.38: Arteriole and Venule Tunica media = single layer of smooth muscle Arteriole (lumen circular) Venule

  14. Slot 5.39: Arteriole, Venule, and Lymph capillary Lymph capillaries Venule Larger lymph vessel Arteriole (thicker tunic media)

  15. Tunica adventitia Slot 5.40: Artery and Vein RBC’s Tunica intima Tunica media Vein Artery

  16. Slot 5.41: Artery and Vein Internal elastic membrane Vein Artery

  17. Slot 5.42: Artery Tunica adventitia Internal elastic membrane Artery lumen Endothelial cells Tunica media
