T-Cells/B-Cells and their functions Flashcards
formed in fetal thymus gland or in bone morrow
t-cell
passes through the thymus on its way to the lymph nodes and spleen
t-cell
formed in fetal bone morrow
b-cell
moves directly to lymph nodes and spleen
b-cell
seek out phagocytes that have engulfed pathogens and examined the antigens of captured pathogens
helper t-cell
divide rapidly to produce memory, cytokine, and suppressor t cells.
sensitized helper t cells
carry the imprint of a particular pathogen antigen and store the imprint in preparation for future invasions of pathogens
memory t cells
chemically rupture the cell membrane of infected cells to prevent the pathogen from reproducing and also produce chemicals called cytokines that attract phagocytosis to the area where the pathogen is located
cytotoxic t cells
suppress the immune response once a foreign antigen has been destroyed
suppressor t cells
reside in the liver, spleen, and lymph nodes until exposed to the antigen of their target pathogen
inactive b cell
divide into memory b cells and plasma cells
activated b cell
remember the antigen and will become involved in responding to any subsequent invasion by that pathogen
memory b cells
produce antibodies specific to a pathogens antigens and tag the pathogens cell for destruction by phagocytosis
plasma cells
