Immune System Flashcards
a forein protein
foreign molecule that the body recognizes as “non-self” and mounts an immune response against it
antigen
protein produced by the body that binds to the antigen and attacks it
antibody
type of white blood cell involved in immunity cell-mediated response uses helper T cells to activate B cells cytotoxic T cells Suppressor T cells
T lymphocytes
type of lymphocyte
cell-mediated response
immune cells that activate B cells
helper T cells
type of lymphocyte
cell-mediated response
kill infected or precancerous cells directly
cytotoxic T cells
type of lymphocyte
cell-mediated response
regulate other immune cells
suppressor T cells
lymphocytes involved in humoral response
plasma and memory cells
produce antibodies
long-lived and allow the body to react quicker the second time it encounters the same foreign body
B lymphocytes
type of B lymphocyte
involved in humoral immune response
produce antibodies
plasma cells
type of B lymphocyte
involved in humoral immune response
long-lived
allow the body to react quicker to the same foreign antigen if it presents itself again
memory cells
type of immunity
long term
immune system response necessary
naturally acquired by exposure to live pathogen
exposure to vaccine w/ weakened or dead pathogens
active immunity
type of immunity
short term
no immune system response involved
naturally acquired-antibodies passed from mother to fetus
injection of gamma globulin containing antibodies
passive immunity
Examples include: allergies (histamine / antihistamine), lupus, MS
Autoimmune problems
type of immunity involving a specific defense
involved B lymphocytes (memory and plasma cells)
humoral immunity
type of immunity
involves cytotoxic T cells, suppressor cells, and helper T cells
cell-mediated immunity
type of immunity
includes skin, passaged lined w/ cilia, macrophages, inflammatory response, and interferons
nonspecific immune response
