1. Acquired Immunity

2. Adaptive/Acquired Immunity
Pathogen-specific
Develops after exposure

3. Lymphocytes
White blood cells produced from stem cells in the bone marrow
B cells – mature in the bone marrow
T cells – mature in the thymus

4. Don’t write

5. Primary Response First time your immune system encounters a pathogen
Involves the production of antibodies that are specific to the pathogen
Antigens – pieces of pathogens that antibodies recognize
Antibodies – immunoglobulin proteins, recognize antigens

7. This process generally take around 2 weeks, during which time you are suffering from the infection
Secondary Response – subsequent exposures to the same antigen, much faster, stronger
When antigen is recognized by memory cells, plasma cells that produce antibodies are mass produced by mitosis
