manipulated. All aspects of body defense, such as antigens and antibodies, allergy, and
hypersensitivity are included.

, active vs. passive

passive immunity
the short-term immunity that results from the introduction of antibodies from another person or
animal (transfer in vivo or colostrum; inclusion of serum/plasma)
active immunity
the immunity that results from the production of antibodies by the immune system in response to
the presence of an antigen (infection; vaccination)
artificial immunity
acquired through a medical procedure such as a vaccine (or infusion of serum/plasma)
natural immunity
any immunity that is acquired through the normal biological experiences of an individual (e.g.
infection; mother's milk)
homeostasis
process by which organisms maintain a relatively stable internal environment
antigen (immunogen)
foreign/organic substance (protein, RNA, DNA, glycoprotein, nucleoprotein) that is large enough
to stimulate an immune response (antibodies)
exogenous
Produced outside the body
endogenous
Produced within the body
