- What is the difference between an allergy and an autoimmune response?In general, what sorts of pathogens might be able to more successfully attack a patient with an inability to synthesize B lymphocytes?Innate lymphoid cells reside primarily in tissues such as the lungs, the lining of the gastrointestinal tract, and the skin, because these sites represent the major routes of entry of pathogens into the body. Several different subsets of innate lymphoid cells exist, and each is specialized to respond to a category of pathogen (e.g., viruses, extracellular bacteria, helminthic parasites, etc). a) True b) False
- Why are lymph nodes often inflamed or swollen when we get sick? a) Your body is producing more white blood cells to fight the infection, and the increase in cell numbers causes them to swell b) The foreign invader is accumulating in your lymph nodes causing them to swell. c) Your body is trying to tell you something is wrong and they swell as an alarm system.Lymph vessel walls are very thin. Why? a) The thin walls allow the bacteria to flow from the lymph to the blood b) The thin walls prevent bacteria from getting trapped in the lymph c) The thin walls allow the inter-cellular fluid to flow into the capillary vesselsAttraction of leukocytes to an inflammatory site is called b) chemotaxis X) margination e) phagocytosis
- Which form of acquired immunity is the patient developing by having this infection? A) Active natural immunity B) Passive natural immunity C) Active artificial immunity D) Passive artificial immunityBoth antibodies and particular complement proteins, such as c3b, are capable of aiding phagocytes in attaching to bacteria. What term best describes these? O 1) opsonins O 2) haptens O 3) pyogens O 4) perforinsWhat distinguishes neutrophils from dendritic cells? How do basophils differ from mast cells?
- What is the immunity of agranulocytes?Based on what you know about the cells of the immune system, do you suspect this patient to have an infection, and if so, what is a probable cause? Choose the best answer and explain. a) Yes, a possible viral infection is indicated. b) Yes, a possible fungal infection is indicated. c) Yes, a possible bacterial infection is indicated. d) No, an infection is not indicated.The correct order of words to describe how innate immune response responds to a pathogen that has gotten by the physical and chemical barriers is: À) Skin, Saliva, Cytokines, Macrophage B)Macrophage, Cytokines, Neutrophil, Natural Killer Cell C) Neutrophil, Cytokines, Killer T Cell, Antibodies D) Antigen, Macrophage, B Cell, Killer T Cell
