Question

Quizplus · Accepted Answer

Lysozyme is an enzyme found in bodily fluids, such as tears and saliva, that breaks down bacterial cell walls. An increase in lysozyme production would be a part of the innate immune response to a pathogen. A decrease in defensin production, choice A, would be the opposite effect of what is expected in an innate immune response. Decreased flow of mucus, choice C, would also be the opposite effect of what would be expected, as mucus traps and helps to remove pathogens from the body. Increased antibody production, choice D, is a part of the adaptive immune response, which takes longer to develop than the innate immune response. Dry skin, choice E, is not necessarily correlated with any specific immune response.
