Why can Memory B-cells react to remembered Memory B-cells already have the proper pathogens faster? antibodies stored up for that pathogen. True or False? True A pathogen can get past the and body’s physical chemical barriers and the inflammation response. What are pathogens engulfed by? Macrophages What is another word for macrophage? Neutrophil What does the macrophage release onto a bacterium The contents of its lysosomes to dissolve it? True or False? True There are still some pieces of the cell bacterium’s membrane left. What are surface proteins of macrophages also Antigens known as? Where does the macrophage force the antigens of the To own cell surface. it’s bacterium? True or False: False. B-cells touch these surface antigens to make a copy Correct cell: Helper T-cells of their shape. Which cell is presented the surface antigen? B-cells B-cells create ________ against pathogens. Antibodies True or False? True Helper T-cells multiply and have two main roles Helper T-cells activate which type of cells? B-cells and Killer T-cells What does the Helper T-cell the B-cells to do? Helper T-cells tell B-cells how to “tell” neutralize the pathogen by presenting the pieces of the bacterium cell membrane. What do the B-cells turn into? Plasma cells Plasma cells multiply and produce _________ to Antibodies; neutralize ________ a specific pathogen What is the second role of the Helper T-cells? To activate the Killer T-cells. What do Killer T-cells secrete? Cytokines True or False? True Killer T-cells can destroy the pathogen itself (bacteria) Why would a Killer T-cell destroy an entire body It is infected with a virus cell? When an immune response is over, what kind of cell Suppressor T-cells stops the process? What do Supressor T-cells some B-cells to do? Suppressor T-cells some B-cells “tell” “tell” (plasma cells) to how to “remember” destroy that specific pathogen B-cells (plasma cells) now become __________. Memory B-cells What is leukemia? And what kind of cell does it Cancer of the blood involving the white involve? blood cells
