- The circulating cytokines that recruit large numbers of phagocytes to the area of inflammation, resulting in pus, are called: O1) pyogens O 2) pyrogens 3) interferons O 4) defensinsarrow_forwardInnate 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) Falsearrow_forwardName two cytokines that are thought to be involved in the inflammatory response to viruses (cite your source). Describe a component of the innate immune response to viral infection (name it and explain how it works. Be sure you are talking about something that protects you from viruses.)arrow_forward
- Describe how phagocytes recognize foreign cells. Explain the mechanism phagocytes use to kill engulfed cells. List some ways pathogens avoid the consequences of phagocytosis. Describe the cause, advantages and disadvantages of fever. Define complement and its role in host defensearrow_forwardThe classical complement pathway involves activation of the complement proteins in which of the following manners? 1) C3b binds to the microbial surface, with factors B, D, and P 2) C1 binds to antibodies bound to the microbe's surface 3) Fungal mannose sugars trigger complement proteins in the blood 4) C3b binds to antibodies bound to the microbial surfacearrow_forwardDraw a figure illustrating the sequence of events in a typical inflammatory response to a bacterial infection caused by injury to the skin (in 3 main stages). Include a note at top of figure: Is this an example of an innate response or adaptive immune response? Include the following structures/cells/chemicals: epidermis, dermis, splinter contaminated with bacteria puncturing skin, macrophages, mast cells, neutrophils, nitric oxide (as blue dots), endothelial cells lining capillary, red blood cells within capillary, histamine (as green dots). Under each stage, describe the events occurring in the 3 main stages: Stage 1: What do mast cells and endothelial cells produce in initial response to injury? What do the chemicals produced by the cells do? Stage 2: What happens to capillaries? What leaks out of capillaries to enter the site of the wound? Stage 3: What do neutrophils and macrophages do? What happens to capillaries at this point?arrow_forward
- Pus is both a sign of infection and an indicator ofimmune defenses in action. Explain.arrow_forwardThe 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 Cellarrow_forwardPart of the complement system of defense is opsonization. This processarrow_forward
- Draw a diagram illustrating the main steps in the inflammatory response.arrow_forwardWhat is opsonization and how does it help phagocytes? Give an example of a molecule that acts as an opsonin.arrow_forwardWhat are some examples of innate defense mechanisms that are chemical in nature? What is complement?arrow_forward
