Immune system

Immune system

1. protein , cell and organs

   • cells of immune system
     • mast cells
       • basophil
     • monocyte
       • macrophage
     • lymphocyte
       • T cells
       • B cells

2. defense system of the individual against the threat

   • first line of defense
     • external barriers
   • second line of defense
     • internal barriers
   • third line of defense
     • specific immune response
       • humoral immunity
         • protection through antibodies
       • cell-mediated immunity
         • protection through sensitized T cells

3. organ of immune system

   • primary of lymphoid organs
     • production sites of immune cells
     • maturation sites for immune cells in the absence of antigen
   • secondary of lymphoid organs
     • maturation sites for antigen-driven immune cells

4. Types of immune system

   • specific immunity
     • specifically recognize foreign antigens and selectively eliminates them
     • reencountering
   • non-specific immunity
     • natural defense system
     • operate nonspecifically
     • natural immunity

5. antigen

   • protein / polysaccharides
   • trigger specific immune response
   • reacts with product of response
   • structure of antigen
     • antigenic determinant site
     • carrier - antigen itself

6. Antibody

   • proteins molecules able to combine with antigenic determinants
   • secreted or membrane bound
   • important component of specific immune response
