Spleen Histology - Cords and Sinuses

  • Blood cells which are emptied into the splenic cords re-enter the blood vessels through the endothelium of the sinusoids.
  • The endothelial cells are elongated (in cross section they may appear cuboidal) and oriented along the long axis of the sinusoids.
  • The endothelium of the sinusoids has no junctional complexes and its basement membrane is incomplete.
    • forming narrow circular bands around the endothelial cells with large intervening fenestrations.
  • Macrophages ingest aged erythrocytes, platelets and other particulate matter as they pass through the splenic cords.
  • The sinusoids continue into the veins of the pulp, which empty into thin-walled trabecular veins, which eventually coalesce to form the splenic vein.
