Lymphatic/ Immune System (Lymph, Lymph vessels and lymph drainage (Lymph…

- - - - drains lymph from the superior right quarter of the body
    - - drains lymph from the rest of the body
- - - - binds with antigens on foreign cells
      - secrete proteins (lyse) that cuts the cells
    - - ( Bone marrow) transform into plasma cell
      - produce antibodies
      - bind with antigen on foreign cells
  - - - bone marrow
        
        red marrow
        
        actively generate blood cells
        
        yellow marrow
        
        dormant, makes blood cells only in emergencies the demand increased hematopiesis
      - thymus
        
        mostly active during youth
        
        hormones, secreted by epithelial reticular cells,signal the contained T lymphocytes to gain immunocompetence.
    - - lymph nodes
        
        destroy pathogens and make memory lymphocytes
        
        a lot of lymphocyte reside there
      - spleen
        
        removes antigens from blood
        
        destroys worn out blood cells
      - tonsils
        
        trap invading cells and destroy them and make memory lymphocytes
      - aggregated lymphoid nodules
      - appendix
        
        MALT abundant
        
        lymphoid tissue is also heavily concentrated in the walls
  - - - in frequently infected mucous membranes of digestive, respiratory, urinary and reproductive tracts, where it is called muscosa associated lymphoid tissues or MALT
  - - - recognizes and acts against a specific foreign molecule
- - - - lymph nodes
        
        lymph trunk
        
        lymph duct
        
        heart
- - - - destroy bacteria by phagocytosis
    - - turn off allergic responses and kill parasties
    - - release histamine and other mediators of inflammation
  - - - mount immune response by direct cell attack or antibodies
    - - phagocytosis develop into macrophages in tissues
