- 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) False1) According to the video, what is another name for the innate immune sys and what does this system do? 2) According to the video, what causes inflammation and what cells cause it? 3) According to the video, what happens to neutrophils after they consume a pathogen? 4) According to the video, natural killer cells; what do they do? 5) The adaptive/acquired immune system can tell the difference between types of pathogens: true or false? 6) According to the video, helper t- function: 7) According to the video, cytotoxic t cells function: 8) According to the video, memory cells function: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…

Here is the options: a) innate immune system. b) adaptive immune system.An allergic reaction is an example of: a) the immune system not working at all. b) a deficiency of B cell responses. c) the immune system doing its job too well. d) an overabundance of T cell responses.The nurse is conducting a class on drugs for malignant tumors for a group of new oncology staff members.
