pathogen
components of the immune system adapt themselves to each new disease encountered and generate this:
pathogen-specific immunity
the immune defense system we are born with
innate/nonspecific immunity
immunity that develops with exposure to various antigens
acquired immunity
any substance foreign to the body that evokes an immune response
antigen
group of immune cells that mediate the immune response by processing and presenting antigens for recognition by certain immune cells
antigen-presenting cells
the interval between exposure to an infectious organism or a carcinogen and the clinical appearance of disease
latent period
APCs include these two cells, that act as messengers between the innate and adaptive immune systems
dendritic cells and macrophages
A type of white blood cell, come in B and T types
lymphocytes
B type lymphocytes produce these
antibodies
T type lymphocytes release these chemicals
cytokines
an effect due to antibodies that are produced in a body other than your own
passive immunity
small doses of an antigen are given to activate this
immune system memory (activated B cells and sensitized T cells)
Chemical that causes blood vessels to leak fluid into tissues, causing swelling
histamine
formed from a collection of dead tissue, dead bacteria, and live and dead phagocytes
pus
an exaggerated immune response to substances that are generally not harmful
allergy
a severe, whole-body allergic reaction to a chemical that has become an allergen
anaphylaxis

tonsils
