Immune (Anatomy (defenses (Adaptive, Innate, cellular immunity, humoral…

- - - - B cells
  - - - red bone marrow
        
        lymph nodes
        
        spleen
        
        peyers patch
        
        appendix
  - - - reticular cells
- - - - may become plasma cells, that secretes antibodies
      - T cells
        
        manage immune response, attack and destroy infected cells or foreign cells
        
        Helper T
        
        regulatory T
        
        calm down T cells to let them know to calm down
        
        memory T
        
        stay after the battle and if same pathogen comes back it will respond quicker
        
        cytotoxic T
        
        actually patrol blood and lymph to KILL cells
        
        activate B and other T cells
      - once activated they turn to effector and memory
      - effector
        
        cells that fight off pathogen by spitting out their antibody to be marked for death
        
        memory
        
        they hang out after the battle and if it sees the same pathogen like before it will react quicker
  - - - capture antigens, and take them to lymph nodes where T cells are
      - Reticular cells
        
        creates fibers in lymph organs
  - - - simplest lymphoid organ
      - tonsils gather and remove pathogens in air and food
      - red bone marrow
        
        B cells mature
        
        lymph nodes
        
        cleanses the lymph
        
        by macrophages
        
        reason why it filters good is because there is less efferent pathways. Gives lymphocytes and macrophages time to get rid of virus
        
        place that activates lymphocytes
        
        by dendritic cell bringing a pathogen
        
        spleen
        
        cleanses blood of old RBCs and platelets
        
        lymphocyte proliferation and immune surveillance
        
        peyers patch
        
        destroy bacteria so it wont breach gut wall
        
        appendix
        
        same as peyers patch
        
        largest lymphoid organ
        
        pulp
        
        white

        cortex (germinal centers)
        
        houses B cells
        
        deep cortex
        
        houses T cells
        
        Medulla
        
        houses B and T cells
        
        b and t cells are born here
  - - - lysogenic
        
        virus injects it DNA to the bacteria cell. But the virus is going to be attached on the bacteria DNA. No destruction. What happens is the cell divides and now the 2 new cells both have a virus on the DNA. It will keep doing that until a disturbance comes along like stress or chemicals then the lytic stage happens.
      - the virus injects its DNA into the bacteria and latch on to the DNA of the bacteria. Then the bacteria DNA is going to be destroyed and the one only left is the virus one. Then viral proteins will be made and more viruses will be made also and then leave the bacteria cell.
  - - - are parasitic. Need living tissue or cells to grow.
        
        to treat this there no specific treatment you can take. you can just do somethings(stay hydrated) while your body fights it off naturally.
    - - can live in almost any environment. are microorganisms.
        
        to treat this is to use antibiotics
  - - - is an advanced version of HIV when its not being controlled. More serious.
        
        make your immune system weak. More likely to get TB, or pneumonia.
    - - Is a virus. Only humans can contract it. It attacks the immune system
  - - - bring a piece of antigen to lymph node to activate b and t cells
    - - create fibers in lymph organs
    - - eat pathogen
    - - release histamine/kinnins for inflammatory response
  - - - is destroying the virus outside the cell. Blood, lymph, between tissues
    - - is destroying the virus inside the cell. the virus made it through all the other defenses.
    - - B cells(humoral immunity)
        
        T cells( cellular immunity)
    - - skin and mucos membrane
  - - - IgD
        
        B cell receptor
      - IgG
        
        most antibodies are in this form 75% to 85%
      - IgA
        
        found in mucus
        
        prevents pathogens from entering
      - IgE
        
        allergies. Cause mast and basophils to release histamines
      - IgM
        
        first one to be released
        
        fixes and activates complement
      - Antibody can switch over to make other type. (most turn to IgG
  - - - mediated cell development
    - - warns other cells
    - - stimulate immune response
