Over years, a virus-infected cell slowly transformed into a cancerous cell exposing (due to mutations) changed antigens, i.e. proteins, on its cell surface. Which of the following cells of the immune system are most likely to recognize and attack this transformed cell? A) tissue macrophages B) neutrophils C) natural killer (NK) cells D) cytotoxic T cells E) plasma cells
Skin Intestine Dendritic Cells Basophils Mouth Lungs Stomach B Cells Macrophages Neutrophils Eosinophils T Helper Cells Cytotoxic T Cells Natural Killer Cells Interferons Complement Antibodies Cytokines Mast Cells Microbiome.: Adaptive immune system components; For each one of the components, indicate: What activates the component and What functions does this component play in the immune defense of the body
A) lymph follicles lymph nodes C) lacteals D) lymphatics 4) An advantage to adaptive immunity is (A) its memory cells that provide quicker, larger and more efficient immune response upon second and subsequent exposure to an antigen B) its need for several cells to be activated over several days on first exposure C) the ability of its individual cells to respond to many different pathogens D) the use of antibodies that cause cell lysis and kill invading cells 5) A...

Drag the terms to the table to match each type of immune system cell with its function. Reset Help Cell type Function secrete antibodies helper T cells B cells stimulate other immune cells cytotoxic T cells destroy body cells that have been infected antigen-presenting cells engulf pathogens macrophages display self-nonself complexes on their surfaces
Which one of the following are incorrectly paired? A. interferons – virus-infected cells B. immunoglobulins – B cells C. class I MHC molecule – CD4 D. perforins – cytotoxic T cells E. perforins - natural killer cells an explanation would be appreciated! thanks!
17. One distinction between B cells and T cells is that A. B cells directly attack an invader while T cells secrete antibodies that attack the invader B. T cells produce antibodies C T cells directly attack an invader while B cells become plasma cells that secrete antibodies that attack the invader D. both cell types attack invaders directly but some B cells differentiate into plasma cells that also simultaneously secrete antibodies
