    • * Fat digestion
    • *Protects the body from bacterial invasion
  4. Afferent
    going into lymph node
  5. Efferent
    Filtered lymph Going out of Lymph Nodes through hilus.
  6. Cysterna Chyli
    An enlargement of the thoracic duct. Receives lymph from lower abdomen, pelvis and lower limbs.
  7. Lacteals
    specialized lymph vessels in small intestine that returns lipids to cysterna chyli.
  8. The thoracic duct is also called
    Left lymphatic duct
  9. what type of fiber are lymph nodes made of ?
    Reticular fiber
  10. what are the indent in the Lymph nodes called?
    Hilus
  11. what is the purpose of reticular fibers in lymph node?
    slow down foreighn invaders for macrophage and lymphocytes to eat
  12. What is the outer layer of the lymph node called?
    Cortex
  13. What is the inner region of lymph nodes called?
    Medulla
  14. What is in sub-capsular Sinus? (free space lymph node)
    • a) Macrophage
    • b)Dendritics cells
  15. What do the dentritic cells do as part of the immune system?
    Initiates immune response
  16. What is in the outer cortex(Germinal Center) of lymph nodes?
    B-cell lymphocytes with plasma and memory cells

    • *Store platelets
    • *can make blood in emergency
  25. Blood clensing fuction of spleen
    removal of bacteria , viruses, toxins, celluar debris
  26. 3 Function of Lymph Nodes
    • 1)Filter foreighn particles from lymph
    • 2)produce and house lymphphocytes
    • 3)House macrophage to engulf and destroy foreighn particles
