What is innate immunity?
Immunity that is active immediately upon exposure to a pathogen whether or not the pathogen has been encountered previously.
Immunity that is active upon exposure to pathogen encountered previously.

What is Class II MHC protein?
Antigen found on antigen presenting cells
Antigen found on infected cells
Antigen found on all cell body
Antigen found on the surface of bacteria
What is the definition of humoral immune response
Immune response involve the production of antibodies by plasma cells
Immune response by T lymphocyte directly attack the cells that carry specific antigen
Immune response by macrophage engulfing pathogen by phagocytosis.
Activated B cells will
Secrete perforin
Secrete granzyme
Proliferate by mitosis to produce plasma cells and memory B cells
Display Class I MHC antigen complex
Activated Tc cells will
Secrete perforin
Secrete granzyme
Secrete antibodies
Display Class II MHC antigen complex
After macrophage engulf a pathogen by phagocytosis it will
Degrade the antigen into antigen fragments
Display the antigen on Class II MHC protein
Secrete interleukin 1 to TH cells
Secrete interleukin 2 to TH cells
