LYMPHATIC/IMMUNE SYSTEM - Coggle Diagram

- - - - Transports fluid around the body called
        
        Lymph
        
        FUNCTIONS
        
        Fluid carried by lymphatic vessels
        
        Harmful materials destroyed or removed
        
        One way system towards the heart
        
        MOVEMENT
        
        Moves by milking action of skeletal muscles surrounding the lymphatic vessels
        
        Rhytmic contraction of the lymphatic vessels
        
        Same forces that move blood in veins
      - Special vessels (Lacteals) transports fat to the circulatory system
    - - LYMPHATIC ORGANS
        
        Lymph nodes
        
        Contain
        
        Macrophages
        
        Lymphocytes
        
        T-Lymphocyte
        
        B-Lymphocyte
        
        Located along lymphatic vessels
        
        Bean shaped, with blood vessels, nerves
        
        Covered with connective tissue that extends inside the node and divides it into
        
        Nodules
        
        Sinuses
        
        FUNCTION
        
        Centers of lymphocyte production
        
        Remove bacteria and cellular debris before lymph is returned to the blood
        
        Macrophages and lymphocytes within lymph nodes filter lymph
        
        Thymus
        
        Spleen
      - LYMPH NODULES
        
        Tonsils
        
        Appendix
        
        Peyer's Patches
- - - - "born with it"
      - Respond rapidly
      - Includes
        
        CHEMICAL BARRIERS
        
        highly acidic and caustic environment provided by
        
        Gastric juice
        
        Lysozyme in teqars
        
        Stimulation of inflammation
        
        NATURAL KILLER CELLS
        
        Type of lymphocyte
        
        Defends body against various viruses and cancer cells
        
        Secrets perforins
        
        MECHANICAL BARRIERS
        
        unbroken skin and mucous membrane of the body create physical barriers
        
        Skin
        
        Hair
        
        Mucus
        
        Sweat
        
        Body's first line defense
        
        INFLAMMATION
        
        Tissue response to a pathogen
        
        Redness, sweeling, heat, and pain
        
        Major actions occur during an inflammatory response
        
        Dilatation of blood vessels
        
        Increase of blood volume in affected areas
        
        Invasion of white blood cells volume in affected areas
        
        SPECIES RESISTANCE
        
        Resistance to diseases that affect other species
        
        PHAGOCYTOSIS
        
        Attracted to the injured areas
        
        Removes foreign particles from the lymph
    - - ANTIGENTS
        
        Anything that can cause an immune response
        
        Generally larger and more complex molecules
      - CYTOKINES AND CHEMOKINES
        
        Cytokines
        
        molecules that signal cells
        
        Used to communicate with other cells to startan it.
        
        Chemokines
        
        Released infected cells to start an immune response
      - IMMUNITY (ACQUIRED IMMUNITY)
        
        Body's third line of defense
        
        Response mounted by the body against specific foreign molecules

        T-LYMPHOCYTES
        
        B-LYMPHOCYTES
- - - - Complement proteins attach to antigen substances
      - EX. bacteria and activates immunity
    - - Act as labels to be identified by immune cells
    - - Some works as antitoxins
      - Block effects of poison produced by certain bacteria
    - - Some clump with other antibodies
      - Form clots in blood
    - - Antigen-antibody complex
      - Becomes so large that it's insoluble and less likely to spread
