The Lymphatic System

  1. 1. The  Lymphatic  System Yuki  TORIBA   Human  Health  Science,  1st  grade   Basics  of  the  Human  Body-­‐E2  Assignment  Topic  3   Monday,  June  12th  2017   1  
  2. 2. Lymphatic  System •  What  is  the  main  function  of  the  lymphatic   system? 2  
  3. 3. Lymphatic  System 3  Patton,  Thibodeau.  Structure  &  Function  of  the  body  15th  ed.  p.319
  4. 4. Lymphatic  System •  Lymph  (lymphatic  fluid)  is  the  excess  fluid   which  is  left  behind  by  capillary  exchange.   •  Lymphatic  vessels  (lymphatics)  are  the   network  of  tubes  which  drain  lymph.   •  Lymph  nodes  are  the  filters  which  lymphatic   vessels  go  through.   •  Lymphoid  organs  are  thymus,  spleen,  tonsils,   Peyer’s  patches,  and  appendix. 4  
  5. 5. Lymphatic  Vessels •  Lymphatic  vessels  do  not  form  the  circular  route.   •  Lymphatic  capillaries  have  close-­‐end  tips.   •  Lymphatic  capillaries  have  flap-­‐like  minivalve  to   permit  large  molecules  go  through.   5   Elaine  N.  Marieb.  Essentials  of  Human  Anatomy  and  Physiology  11th  ed.  p.400
  6. 6. Lymphatic   Vessels •  Lymph  finally  flows   into  the  right   lymphatic  duct  or  the   thoracic  duct,  which   return  their  lymph   into  the  blood  in   large  veins  in  the   neck  region.   •  Lymph  from  about  ¾   of  the  body  drains   into  the  thoracic   duct,  which  is  the   largest  lymphatic   vessel  in  the  body.   6   Patton,  Thibodeau.  Structure  &  Function  of  the  body  15th  ed.  p.318
  7. 7. Lymphatic  Vessels  in  Small  Intestine •  Lymphatic  capillaries   in  the  wall  of  small   intestine  are  given   the  special  name  of   lacteals.   •  They  transport  fatty   acid  which  obtained   from  food  to   bloodstream.   7   Patton,  Thibodeau.  Structure  &  Function  of  the  body  15th  ed.  p.377
  8. 8. Lymph  Nodes •  First,  debris  is   trapped  by  the   web  of   reticular  fibers.   •  Second,   immune  cells   destroy  the   debris  by   phagocytosis.   •  Efferent   lymphatic   vessels  are  less   than  afferent   lymphatic   vessels.   •  Why?   8   Elaine  N.  Marieb.  Essentials  of  Human  Anatomy  and  Physiology  11th  ed.  p.402
  9. 9. Lymphoid   Organs  -­‐   Thymus •  source  of  lymphocyte   before  birth   •  T  lymphocyte   maturation  cite   •  up  to  40  grams   •  Half  of  the  thymus  is   replaced  by  fat  and   connective  tissue  by   age  60,  and   completely  replaced   by  age  80,  which  is  a   process  called   involution.   9   Patton,  Thibodeau.  Structure  &  Function  of  the  body  15th  ed.  p.318
  10. 10. Lymphoid   Organs  -­‐   Spleen •  the  only  lymphoid   organ  which  treats   blood   •  blood  filtration   •  worn  out  red  blood   cell  destruction   •  iron  recycling   •  blood  reservoir  which   can  contain  more   than  500  mL   •  the  largest  lymphoid   organ   •  But  we  can  survive   without  spleen   10   Patton,  Thibodeau.  Structure  &  Function  of  the  body  15th  ed.  p.318
  11. 11. Lymphoid   Organs  -­‐   Tonsils •  protect  against  bacteria   which  may  invade   tissues  in  the  nasal  and   oral  cavity   •  Pharyngeal  tonsils  are   called  adenoid  when   they  become  swollen.   11   Patton,  Thibodeau.  Structure  &  Function  of  the  body  15th  ed.  p.322
  12. 12. Lymphoid   Organs  –   Peyer’s   patches •  resemble  tonsils   •  in  the  wall  of  the   small  intestine,   mainly  in  distal  parts   12   Elaine  N.  Marieb.  Essentials  of  Human  Anatomy  and  Physiology  11th  ed.  p.403
  13. 13. Lymphoid   Organs  –   Peyer’s   patches •  mean  number   of  Peyer’s   patches  is  70   before  birth   and  160  in   children.     •  They  define   Peyer’s   patches  as   patches   containing   more  than  5   follicles   (nodeules).   13   J.  S.  Cornes.  Number,  size,  and  distribution  of  Peyer's  patches  in  the  human  small  intestine.  Gut.  1965  Jun;  6(3):  225–229.  
  14. 14. Lymphoid   Organs  –   Appendix •  a  tubelike  offshoot   of  the  first  part   (cecum)  of  the  large   intestine.   14   Elaine  N.  Marieb.  Essentials  of  Human  Anatomy  and  Physiology  11th  ed.  p.403
  15. 15. Lymphoid  Organs •  Thymus  is  T  cell  maturation  site.   •  Spleen  is  blood  filter  and  destroy  worn  out  red   blood  cell  and  recycle  iron  in  hemoglobin.   •  Tonsils,  Peyer’s  patches  and  appendix  are   called  mucosa-­‐associated  lymphoid  tissue   (MALT).   •  MALT  is  a  sentinel  which  protect  the  upper   respiratory  tracts  and  digestive  tracts. 15  
  16. 16. Lymphatic  System •  What  is  the  main  function  of  the  lymphatic   system?   •  removal  of  interstitial  fluid   •  physical  and  biological  filtration   •  white  blood  cell  formation  &  maturation   •  fatty  acid  absorption  in  intestine   16
