Which of the following is NOT one of the major functions of T lymphocytes (T cells)? activating the immune system binding to antigens presented by MHC proteins production of antibodies forming memory cells to more rapidly respond to future infections by the same pathogen attacking our own cells that are infected with a virus or cancerous

Which of the following is true about the innate immune system? Check all that apply Phagocytosis is an adaptive immunity component required for elimination of microbes Innate immune cells are macrophages and dendritic cells that engulf pathogens but also present antigen to T lymphocytes Innate immunity improves with repeated infections Neutrophils are the abundant innate immune cells circulating in blood Innate immune system provides protection immediately after infection in a non-specific manner
Which of the following defines a memory cell? Microorganism that typically lives on the human body surface Self-protein on the surface of a vertebrate body cell Antigen-sensitized lymphocyte that forms in an immune response and acts immediately Long-lived antigen-sensitized lymphocyte that can act in a secondary immune response
Which of the following is mismatched? Epitope - Specific area on an antigen that interacts with antibody Acquired (or Adaptive) Immunity - innate, nonspecific resistance to infection; present at birth Antigen - Substance that provokes a specific immune response Susceptibility - Lack of resistance to a disease Antibody - Protein made in response to an antigen which can specifically bind to that antigen
Which is/are false about innate and specific immunity? B cells are part of the innate immune system T cells activate B cells and cause them to undergo clonal expansion Langerhans cells are specialized to detect pathogens in the skin Eosinophils are part of the innate immune system
Which of the following is NOT a component of the adaptive (specific) immune system? cytotoxic T cells antibodies helper T cells memory B and T cells neutrophils
Which of these is an incorrect description of either the adaptive or innate immune responses? Innate immunity involves both surface barriers and internal defenses. Only adaptive immunity involves defense against a specific foreign invader. Inflammation is an innate immune response but not an adaptive immune response. Chemicals are involved in adaptive immunity but not innate immunity. Immune system cells play a role in both innate and adaptive immune responses.
Which of the following types of immunity is responsible for preventing pathogens from entering the cell? antibody-mediated (Humoral) immunity OOOO sarcoplasmic immunity pathogenic immunity cell-mediated immunity
The body’s immune response comprises innate immunity and adaptive immunity. Virulence is the capacity of a pathogen to cause disease BOTH statements are FALSE BOTH statements are TRUE FIRST statement is FALSE; SECOND statement is TRUE FIRST statement is TRUE; SECOND statement is FALSE
Which of the following is not a component of an autoimmune response? The body's immune system targets its own tissues. Lymphocytes are produced that cannot discriminate between self and nonself. A normally harmless substance provokes an immune response in some people. An autoimmune response may be triggered by infection by a bacterium or virus such as HIV.
