The Adaptive Immune Response Is a Specific Defense Against Infection Compare the general inflammatory response, the complement system, and the specific immune response.
Figure 42.11 Which of the following statements about T cells is false? Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells.

Match the immune cell with its main function. ___dendritic cell a. professional phagocyte ___B cell b. antigen-presenter ___helper T cell c. activates other lymphocytes ___NK cell d. makes antibodies ___macrophage e. kills ailing body cells that lack MHC markers
Put the following steps in order for cell-mediated immunereactions:(a) Differentiated T cells include T helper, delayed hyper-sensitivity, cytotoxic, and memory T cells that all havedifferent immunological functions depending on the an-tigen presented.(b) Antigen-presenting cells (macrophages and dendriticcells) phagocytize pathogens, ingesting and degradingthem into pieces which are transported to the surface ofthe cell.(c) T cells bearing the corresponding receptor for the pre-sented antigen bind to it and become activated only ifthe appropriate MHC is also present.(d) Some pieces of the pathogen’s antigens are processedby inserting them into the antigen-presenting cell’smembrane and are held in place by class II majorhistocompatibility complex (MHCII) proteins.(e) Activated T cells are stimulated to divide and differen-tiate into different types of T cells, including memorycells
Using words and arrows, complete a flow outline of an immune response, beginning with entrance of antigen; start with the response of the innate immune system, describe antigen processing, cell interaction, involvement of cytokines, and the end results for B and T cells.
The adaptive immune defenses respond to which of the following?a. specific antigensb. general pathogensc. interferond. histaminee. All of these are correct.
Which of the following is part of the second line of defense? a. Interferons b. Phagocytes c. Macrophages and histiocytes d. Inflammatory reactions e. Fever f. Complements Please provide answer in short asap!!
It is well known that immune response requires interaction betweenimmune system cells. Please explain how dendritic cells mediate immuneresponse by interacting with other immune system cells.
Select all of the following statetments that apply to immunological memory: A. A small population of plasma cells secrete pathogen-specific antibody long after pathogen clearance from the body. B. Memory T cells and memory B cells originate in secondary lymphoid tissue through colonal expansion. C. Memory T cells are produced during secondary immune responses, but not during primary immune responses. D. During a primary immune response, effector B cells outnumber memory cells. E. protective immunity persists for the same period regardless of the type of pathogen F. Memory B cells generated in secondary immune responses are more effective than memory B cells made in primary immune responses because of affinity maturation
