Helper T Cell

Front

Set off an alarm to the immune system that pathogens have broken through the body's line of defense; activates B cells

Back

Lymphocyte

Front

White blood cell

Back

Passive Immunity

Front

Temporary immunity where antibodies are transferred from another animal ex: mother transfers some of her antibodies to her nursing child

Back

Innate Immunity

Front

Quick and non-specific, providing a generalized protection from most intruding organisms and toxins. (skin, macrophages)

Back

T Cells

Front

Cell-mediated immune response, stimulated by antigen-presenting cells (macrophages).

Back

B Cells

Front

Humoral response by producing antibodies; activated by T cells or free antigens

Back

Phagocytes

Front

White blood cells that engulf invading pathogens e.g., neutrophils, macrophages

Back

Adaptive Immunity

Front

The ability, obtained during the life of the individual, to produce specific antibodies and T cells

Back

Killer T Cell

Front

Kills body cells that have been infected with pathogens; stimulated by antigens and helper T-cells

Back

Memory Cells

Front

Responsible for lifelong immunity by storing copy B cells to more quickly fight secondary infection

Back

Macrophages

Front

Antigen-presenting cell that engulfs large numbers of pathogens; presents antigen to activate T cells

Back

Antibody

Front

Y-shaped protein with variable antigen bind region; slows pathogens to facilitate destruction

Back

Antigen

Front

Identifying marker on the outside of a pathogen

Back
