  • ANOTOMY OF THEANOTOMY OF THELYMPHATICSLYMPHATICSLymphatic system consist of:-Lymphatic system consist of:-1)1) Peripheral lymph vessels ( consist of single layer ofPeripheral lymph vessels ( consist of single layer ofattenuated endothelial cells, no basementattenuated endothelial cells, no basementmembrane)membrane)2)2) Lymph nodesLymph nodes3)3) Major lymphatic trunksMajor lymphatic trunksFUNCTIONFUNCTION:- primary function is to transport extracellular fluid:- primary function is to transport extracellular fluidfrom the interstitial space back to blood stream, act asfrom the interstitial space back to blood stream, act asprotective filter against foreign body invasionprotective filter against foreign body invasionTotal lymph return to the venous circulation in 24 hours aboutTotal lymph return to the venous circulation in 24 hours about2-4 liters.2-4 liters.

  • 21-21-99Mechanisms of Lymph FlowMechanisms of Lymph Flow Lymph flows at low pressure and speedLymph flows at low pressure and speed Moves along by rhythmic contractions of lymphaticMoves along by rhythmic contractions of lymphaticvesselsvessels stretching of vessels stimulates contractionstretching of vessels stimulates contraction Flow aided by skeletal muscle pumpFlow aided by skeletal muscle pump Thoracic pump aids flow from abdominal to thoracicThoracic pump aids flow from abdominal to thoraciccavitycavity Valves prevent backward flowValves prevent backward flow Rapidly flowing blood in subclavian veins, drawsRapidly flowing blood in subclavian veins, drawslymph into itlymph into it Exercise significantly increases lymphatic returnExercise significantly increases lymphatic return
  • LymphedemaLymphedema Excessive and persistent accumulation ofExcessive and persistent accumulation ofextravascular and extracellular fluid and proteinsextravascular and extracellular fluid and proteinsin tissue spacesin tissue spaces Caused by a disturbance of the water andCaused by a disturbance of the water andprotein balance across the capillary membraneprotein balance across the capillary membrane Increased concentration of proteins drawsIncreased concentration of proteins drawsgreater amount of water into interstitial spacesgreater amount of water into interstitial spaces Exceeds transport capacity of the lymphaticExceeds transport capacity of the lymphaticsystem, leading to lymphedemasystem, leading to lymphedema
  • Disorders of the Lymphatic SystemDisorders of the Lymphatic SystemLeading to Lymphatic InsufficiencyLeading to Lymphatic Insufficiency Primary (Congenital) MalformationPrimary (Congenital) Malformation Infection and InflammationInfection and Inflammation Obstruction or FibrosisObstruction or FibrosisTrauma, Surgery, NeoplasmsTrauma, Surgery, NeoplasmsRadiation TherapyRadiation Therapy Surgical Dissection of Lymph NodesSurgical Dissection of Lymph Nodes Chronic Venous InsufficiencyChronic Venous Insufficiency
