- - - - mucus contains lysozymes (antimicrobial enzymes) and phagocytes
  - - - types
        
        neutrophil
        
        does phagocytosis
        
        macrophage
        
        does phagocytosis
        
        antigen presentation
        
        monocyte
        
        dendritic cells
      - phagocytosis
        
        the act of engulfing a pathogen or non-self substance, the bulk movement of this substance into the cell
    - - inflammation
        
        secretes histamine
        
        causes vasodilation
        
        increases permeability of capillaries
  - - - B lymphpocytes
        
        humoral response
        
        types
        
        plasma cell
        
        produce and secrete antibodies
        
        memory cell
        
        retain a memory of the antigen and move around lymph
      - T lymphocytes
        
        cell-mediated response
        
        types
        
        T helper cell
        
        secretes interleukins to stimulate cloning
        
        T killer cell
        
        lysis of infected cells
        
        using perforins
        
        T regulator cell
        
        stop immune response after it has been successful
        
        T memory cell
        
        retain a memory of the antigen and move around the lymph
  - - - when the body has made the antibodies and memory cells for the specific antigen
  - - - antitoxins
      - opsonination
      - agglutination
- - - - communicable
        
        caused by pathogens, like bacteria, protoctists, fungi and viruses
        
        can be passed on from one host to another
        
        examples
        
        AIDS
        
        tuberculosis

        COVID-19
        
        meningitis
        
        thrush
      - non-communicable
        
        cannot be passed on from one host to another
        
        not caused by pathogenic organisms
        
        examples
        
        emphysema
        
        rickets
        
        scurvy
        
        asthma
        
        diabetes
        
        cystic fibrosis
        
        CHD
