front 1 You note that the body temperature of one of your patients is starting to increase. As a result, you can infer that all of the following may be occurring in this patient EXCEPT __________. | back 1 dilation of blood vessels |
front 2 Which statement regarding the lymphatic system is true? | back 2 Lymphatic capillaries possess one-way valves. These valves permit the uptake of fluid from the body but do not allow the fluid to flow back out of the capillaries into the intracellular spaces. |
front 3 What does the plasma membrane of a phagocyte attach to on a microorganism? | back 3 Glycoproteins |
front 4 The process by which a phagocyte moves toward a chemical signal at the site of an infection is called | back 4 chemotaxis. |
front 5 Which of the following phagocytic processes occurs last in the sequence? | back 5 Exocytosis |
front 6 What is the role of opsonins? | back 6 They create "handles" that make it easier for the pseudopods of phagocytes to attach to the microbe invader. |
front 7 What is a phagolysosome? | back 7 The structure that results from the fusion of a phagosome and a lysosome. |
front 8 Which of the following statements about innate immunity is true? | back 8 Innate immunity is present at birth. |
front 9 Which of the following statements concerning phagocytosis is true? | back 9 Bacteria are digested when the phagosome fuses with a lysosome. |
front 10 Innate immunity | back 10 is nonspecific and present at birth. |
front 11 All of the following protect the skin and mucous membranes from infection EXCEPT | back 11 HCl. |
front 12 Which of the following exhibits the highest phagocytic activity? | back 12 macrophages |
front 13 A child falls and suffers a deep cut on her leg. The cut went through her skin and she is bleeding. Which of the following defense mechanisms will participate in eliminating contaminating microbes? | back 13 phagocytosis in the inflammatory response |
front 14 Which of the following statements is TRUE? | back 14 Gamma interferon causes bactericidal activity by macrophages. |
front 15 Which of the following is an effect of opsonization? | back 15 increased adherence of phagocytes to microorganisms |
front 16 Which of the following statements about fixed macrophages is FALSE? | back 16 They develop from neutrophils. |
front 17 Phagocytes utilize all of the following to optimize interaction with microorganisms EXCEPT | back 17 lysozyme |
front 18 All of the following are effects of histamine EXCEPT | back 18 fever. |
front 19 Activation of C3a results in | back 19 acute inflammation. |
front 20 Digestion of microorganisms occurs in phagosomes. | back 20 False |
front 21 Complement proteins act as opsonins by binding to microorganisms and promoting phagocytosis. | back 21 False |
front 22 Microorganisms that are members of the normal microbiota are also known to cause disease. | back 22 True |
front 23 Which non-specific defense mechanism is mismatched with its associated body structure or body fluid? | back 23 mucociliary escalator intestines |
front 24 All of the following occur during inflammation. What is the first step? | back 24 vasodilation |
front 25 Innate immunity includes all of the following EXCEPT | back 25 production of antibody. |
front 26 Each of the following provides protection from phagocytic digestion EXCEPT | back 26 formation of phagolysosomes. |
front 27 All of the following increase blood vessel permeability EXCEPT | back 27 lysozymes. |
front 28 Activation of C3 results in __________. | back 28 all of these- release of histamine and other pro-inflammatory chemicals, formation of a membrane attack complex (MAC), which causes cytolysis of bacteria, enhancement of phagocytosis via opsonization. |
