Step by step
Solved in 2 steps
- What is the difference between an allergy and an autoimmune response?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. An autoimmune response may be triggered by infection by a bacterium or virus such as HIV. A normally harmless substance provokes an immune response inThe 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 a FALSE statement about innate immunity? Natural killer cells are participants in the process It must be primed by the presence of a specific antigen It includes inflammatory responses It may involve the formation of complement protein cascades It includes physical and chemical barriersWhich of the following statements is true of acquired immunity? It does not involve experience and its forms include phagocytosis and inflammation. Acquired immune responses take longer to initiate than natural immune responses. An effective immune response occurs even before prior exposure to a particular antigen. It consists of a number of inborn processes that help remove foreign substances from the body.Many human epithelial cells produce sticky mucus. Which of the following statements best describes how this mucus functions in nonspecific adaptive immunity? assists in the physical removal of pathogens from the body produces antibodies that will cause pathogen lysis promotes growth of the body's normal microbiota provides an impenetrable outer covering that cannot be penetrated by most pathogens
- 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 mannerWhich of the following is NOT an example of non- specific (innate) resistance mechanisms interacting directly with specific acquired immunity mechanisms? Complement being activated by antigen- antibody binding Macrophages and dendritic cells presenting antigens to lymphocytes Antibodies binding to bacterial surface antigens, coating (opsonizing) the bacteria and enhancing their phagocytosis by leukocytes None of the other four answers (All are examples of interaction between innate and acquired resistance) Antibody-dependent cell-mediated cytotoxicityAll of the following are true of the lymphatic system, EXCEPT: Lymphatic capillaries lie in close physical proximity to arterial and venous capillaries None of the other four answers (all are true of the lymphatic system) Lymph nodes are located at lymphatic vessel junctions It brings microbial antigens into contact with immunologically active cells (lymphocytes and macrophages) Its only important function is to carry interstitial fluid back to the circulatory system
- Which of the following occurs during an active immunization? Effector and memory cells do not form. A preparation of antibodies is provided to an individual who was already exposed to a lethal agent. A preparation of a specific antigen is provided to a patient to induce immunity by forming effector and memory cells.Which of the following is a mechanism by which antibodies help rid the body of invading microbes? Agglutination whereby the bacteria are clumped together. Identifying viruses for elimination by NK cells Non-antibody dependent activation of complement Autoimmune diseaseWhen referring to immunity, what does the term innate imply? the mechanism will develop based upon exposure to specific pathogens the mechanism will be built-in and present at birth the mechanism will be acquired over an individual's lifetime the mechanism will provide defense against many different types of pathogens
