Chapter 13 - Immunity Chapter 13 Immunity Multiple Choice Questions 1. The fact that a person does not contract potato nematode infections is due to a. Acquired immunity b. Possessing antibodies to the nematode C. Being naturally resistant d. Possessing a cellular defense system e. Premunition 2. In the case of ___________, immunity is sufficient that a host can recover and be generally resistant, but some parasites remain and reproduce slowly. a. Allergy b. Allergic response c. Inflammation d. Innate immunity E. Premunition 3. Low-molecular weight glycoproteins that are released by many eukaryotic cells in response to invasion by intracellular parasites are a. Complement b. Lysozymes c. Macrophages D. Interferons e. Tissue necrosis factors 4. _________________ is produced by macrophages and is a mediator of inflammation and may help cause fever. a. Complement b. Lysozymes c. A major histocompatibility complex d. Interferon E. Tumor necrosis factor 35-1 Chapter 13 - Immunity 5. _________________ is/are a series of enzymes activated in a sequence as a response to invading organisms. A. Complement b. Lysozymes c. A major histocompatibility complex d. Interferons e. Tumor necrosis factors 6. When a phagocyte engulfs a bacterium or other foreign particle, how does it destroy the foreign material in the vacuole? a. By being denied its natural food and surface respiration the bacterium simply ceases to live and breaks apart over time b. The phagocyte's nuclear coding is stronger than that of the bacterium c. The Golgi body proceeds to use molecules from the foreign body for cell products D. A cell lysosome is fused with the foreign particle and digestive enzymes destroy the particle e. Cell mitochondria use the foreign material as a fuel for aerobic respiration 7. What type(s) of cell(s) conduct(s) phagocytosis? a. Macrophages in lymph nodes b. Kupffer cells in sinusoids c. Microglial cells in the brain d. Neutrophils E. All of the choices are able to phagocytize 8. Neutrophils and lymphocytes are types of a. Platelets b. Red blood cells C. White blood cells d. Plasma cells e. Epithelial cells 35-2 Chapter 13 - Immunity 9. The terms "neutrophil" and "basophil" and "eosinophil" refer to a. Whether they are active in acidic, neutral, or basic conditions b. Their tissue origins c. The type of chemical they use to kill cells D. Stains that are used to identify them e. The researchers who described them 10. A high eosinophil count is associated with a. Allergic diseases and parasitic infections b. Influenza infections c. Bacterial infections d. Protozoan infections E. All of the choices produce this symptom 11. Which statement is NOT true about neutrophils? a. They are phagocytic b. They are polymorphonuclear C. They are made in lymphoid tissue d. They do not produce antibodies e. They are the most abundant white blood cell 12. The acquired immune response in vertebrates has two arms, a. Antibodies and antigens b. B and T lymphocytes C. Cellular and humoral d. TH1 and TH2 e. Immunoglogulins and T-cell receptors 13. Immunoglobulins have a structure that resembles the letter a. A b. B c. S d. T E. Y 35-3 Chapter 13 - Immunity 14. The molecular basis for nonself recognition is in the highly variable ________ that is imbedded in the cell surface. a. Antibody b. Immunoglobulin c. Granulocyte D. Major histocompatibility complex e. Epitope 15. When an antibody becomes coated with antibody molecules and the macrophages recognize the projecting antibody regions and are stimulated to engulf the particle, this process is called a. Co-receptor toxicity b. Cytokinesis c. Antigen-presentation D. Opsonization e. Inflammation 16. Which of the following statements is correct? a. Inflammation is a very specific response to a limited number of antigens b. All immune responses involve antibodies c. There are an equal number of memory cells and activated B cells that gave rise to the memory cells D. Inflammation is a vital process to defend and repair tissues e. All of the choices are correct 17. Immediate hypersensitivity is a. Antibody mediated b. Due to degranulation of local mast cells c. A cause of anaphylaxis that can be fatal d. The basis for allergies and asthma E. All of the choices are correct 35-4 Chapter 13 - Immunity 18. Pus consists of a. Antigen and plasma b. Antibody and tissue fluid C. Dead leukocytes and tissue fluid d. Dead mast cells and plasma e. Interleukin-II and interferon 19. To make snakebite antivenin, we inject a horse with increasing doses of venom and then extract the horse's antibodies and inject them inside a person who has been bitten by a snake in order to save his/her life. a. The antivenin builds a person's active immunity B. The antivenin presents the antibodies built by the horse and is soon eliminated itself by the person's immune system c. The antibodies form a permanent immunity in the person against the venom d. The victim forever has horse serum antivenin in his/her blood e. None of the choices are correct 20. The blood typing test relies on ________ of red blood cells. A. Agglutination b. Staining c. Microscopic inspection d. Culturing e. Nuclear identification 21. Why does A-type blood have anti-B antibody and B-type blood have anti-A antibody in a young individual who has never been exposed to a blood transfusion? a. The fetus is exposed to the mother's blood antigens during pregnancy b. All individuals already have all possible antibodies at birth so this is normal C. The theory is that antibodies develop to A and B epitopes on intestinal microorganisms in the intestine d. The antibodies are transferred in the saliva from parent to child e. The antibodies are made to the recessive blood type that is not expressed 35-5
