1): Basic functions of lymphatic system Lymphatic system: structure (also covered in lab) • network of lymph vessels and organs/tissues •lymph nodes (~600) at intervals along vessels Primary lymphatic organs/tissues • site where immunocompetent cells develop e.g. red bone marrow, thymus Secondary lymphatic organs/tissues • sites immune responses occur e.g. spleen, lymph nodes and nodules, nsils, appendix, Peyer’s patches (SI) HKin 191 2 tonsils, appendix, Peyer’s patches (SI)

1): Basic functions of lymphatic system 1) Draining interstitial fluid • drains interstitial fluid • interstitial fluid forced out of capillaries by hydrostatic pressure 3 liters/day accumulates between cells • ~ 3 liters/day accumulates between cells • draining also recovers macromolecules ( e.g . proteins) lost in interstitial fluid • drainage through lymphatic capillaries b lymphatic circulation b blood lymphatic capillary HKin 191 4

1): Basic functions of lymphatic system 1) Draining interstitial fluid • lympathic vessels: thin walled, non-muscular, hollow transport vessels • lymphatic circulation driven by muscle pumps ~ 120 ml/hr • skeletal muscle (compression by skeletal muscles contraction) • respiratory pump (compression by thoracic expansion/contraction) • unidirectional flow maintained by flap (passive) valves (like veins) HKin 191 5
