- 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) FalseWhat sorts of pathogens could successfully attack a patient who is unable to produce T lymphocytes?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
- 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) defensinsWhich of the following lists contains cells that are typically considered to be associated with the innate immune response? Question 14 options: A) neutrophils, macrophages, T cells B) neutrophils, macrophages, NK cells C) B cells, T cells, and NK cells D) basophils, T cells, mast cellsBoth 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) perforins

C)A vaccination is an example of the introduction of passive immunity into the body.What is the role of histamine in inflammation? A)Histamine increases the volume of blood flow in the area of the infection. B)All these choices are correct. C)Histamine signals to neutrophils to migrate to the site of infection. D)Histamine makes it easier for neutrophils to move from the bloodstream to the site of infection.Name four types of lymphocytes involved in cellularimmunity. Which of these is also essential to humoralimmunity?
- 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.i) True or False : Antibodies attach firmly to an antigenic determinant called an epitope.ii) True or False: Band T-cells are the components of the adaptive immune system.iii) True or False: Swelling, redness, and pain of the injured part are due to inflammation of the injured tissue.iv) True or False: Insertion of complement proteins C7, C8, and C9 into the cell membrane of the pathogen is due to the Amphipathic nature of these proteins.v) True or False: During inflammation cells from the adaptive immune systems are mainly recruited towards the site of infection.vi) True or False: Cytokines are released by Macrophages for the killing of the Ag directly.vii) True or False: Macrophages always mature into monocytes at the site of infection.viii) True or False: All components of the Complement systems remain active in the body all the time.ix) True or False: All the factors of the complement system remain active except factor-D due to its substrate specificity for factor-B, bound to…In a normal individual, a T cell that interacts with a self-antigen in the thymus will more than likely undergo what process (which answer is best)?
