Acquired Immunity

Acquired immunity is not necessarily present at birth, rather it matures later in life due to its "memory" characteristic. Since it is antigen-specific, the "memory" allows for greater response against the same antigen if it were present in the body again. It must be induced for a response to occur.
Includes Active and Passive immunity
Active immunity involves the individual making his/her own immune products
Passive immunity involves giving immune products to an individual (i.e. vaccination, antidote)
Active immunity is split into Humoral and Cell Mediated Immunity
Humoral Immunity contains B cells which produce antibodies against extracellular bacteria and toxins
Cell Mediated Immunity contains T cells which produce cytokines against intracellular bacteria, viral infections, and cancer cells.
