Question 27 options: Antigen processing Inflammation Sensitization Hyperreactivityquestion 39 CD4 cells are cells and CD8 cells are cells A killer, suppressorB helper, cytotoxicC cytotoxic, helperD B,TQuestion 1 Nursing. 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

From the drop down boxes, choose the correct letter (A -- Programmed or B -- Stochastic). Celluar Aging: suggesting that the lifespan of a species is determined by an internal cellular "clock" that limits the number of cell divisions. Immune System: suggesting that aging is due to a break-down in the body's natural defense system against bacteria, viruses, and other substances. Error Theory: suggesting that errors at the cellular level produce "faulty" molecules. Evolutionary theory: suggesting that aging is a natural way to limit the reproductive potential and timespan of members of a species. Wear and Tear: suggesting that like a battery or a machine, the human…
