True or False 1. In phagocytosis, the digestion of phagocytes is always complete  2. The second line of defense is a specific immune response that responds against a specific type (species or strain) of pathogen.  3. Eosinophils can phagocytize and this is their usual mode of attack.  4. The body’s initial line of defense is made up of chemicals, and processes that work together to prevent pathogens from entering the body in the first place.  5. In general, beta and gamma interferons are present early in viral infections, whereas alpha interferon appears somewhat later in the course of infection.  6. The second line of defense is chiefly composed of external physical barriers to pathogens, especially the skin and mucous membranes.  7. The chemicals involved assist phagocytic cells either by directly attacking pathogens or by enhancing other features of specific resistance.  8. The combination of the barrier function of the dermis including its continual replacement and the presence of…

Question 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

Case Study Analysis 4.2 Explain natural/acquired immunity and active/passive immunity 4.3 Explain the basis of immunisation and evaluate its efficacy in a range of contexts 4.4 Explain essential differences between humoral and cellular responses as shown by B-lymphocytes and T-lymphocytes For each of the scenarios below state whether the immunity gained is active or passive, and natural or acquired. Justify your answer and explain how immunity is gained in each scenario. Where relevant use data and image to support your explanation. Make sure your explanations meet all the above criteria (AC 4.2, 4.3, 4.4). Case study 1: Julia has a new baby and has received the vaccination schedule from the GP which includes the MMR. Julia is nervous about giving her new infant the vaccination as it makes use of attenuated forms of the three viruses and asks the GP whether it is essential. Explain to Julia why the MMR is important and evaluate the effectiveness of the vaccine. ​with references
