Describe the role of non-specific macrophages in preventing infection
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
Which is true regarding the innate immune system?
A) O Opsonization is responsible for destroying virus-infected cells.
B) OPeyer's patches are part of your adaptive immune system that serves to help in antibody formation
C)O Your microbiota consists of billions of bacteria that are found in (and on) every part ofyour body
11
D) O Your innate immune system is generally faster acting than your adaptive immune system.
E) O Microbial antagonism the mechanism by which pathogens are able to colonize your body

- Define pathogen.arrow_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_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_forward
