The lympathics system includes a network of tissues and organs, which carry the cells and molecules that respond as/ on behalf of the body's immune system. Structures like the thymus and lymph nodes are integral to the adaptive immune response, since cells of the adaptive immune response are either created or stored there until non-self invaders are recognized and cause activation. True or False

The Adaptive Immune Response Is a Specific Defense Against Infection Identify the components of cellular immunity, and define their roles in the immune response.
The Adaptive Immune Response Is a Specific Defense Against Infection Name the class of molecules that includes antibodies, and name the five groups that make up this class.
All of the following are true of antigen-presenting cells (APCs) EXCEPT: which option below is the answer? None of the other four answers (All are true statements about APCs) They can interact directly with lymphocytes They include macrophages and dendritic cells APCs by themselves cannot distinguish between different microbial antigens, remember them later, or respond specifically to them They are non-specific cells and they play no role in activating or triggering specific immune responses
The immune system can be split into two major categories, the innate immune system and the adaptive immune system. Compare and contrast these two systems and their response to a bacterial pathogen that entered the body through a cut in the skin. In your answer describe two ways in which the innate immune system protects against this pathogen, as well as two ways that the adaptive immune system protectS against this pathogen. Be sure to name any cells/organs/tissues/structures that may be involved in each of these processes in order to receive full marks. This can be done as a list in point form.
True/False: Dendritic cells are tissue resident myeloid cells that are highly phagocytic, like macrophages. However, dendritic cells do not play a major role in large-scale pathogen destruction; instead, they are important in initiating adaptive immune responses of T cells.
All of the following are true of the lymphatic system, EXCEPT: Lymphatic capillaries lie in close physical proximity to arterial and venous capillaries None of the other four answers (all are true of the lymphatic system) Lymph nodes are located at lymphatic vessel junctions It brings microbial antigens into contact with immunologically active cells (lymphocytes and macrophages) Its only important function is to carry interstitial fluid back to the circulatory system
Which of the following is NOT an example of non- specific (innate) resistance mechanisms interacting directly with specific acquired immunity mechanisms? Complement being activated by antigen- antibody binding Macrophages and dendritic cells presenting antigens to lymphocytes Antibodies binding to bacterial surface antigens, coating (opsonizing) the bacteria and enhancing their phagocytosis by leukocytes None of the other four answers (All are examples of interaction between innate and acquired resistance) Antibody-dependent cell-mediated cytotoxicity
The response to intracellular pathogens, by the innate immune system is the same as the response to extracellular pathogens, including phagocytosis, inflammation, and/or extracellular killing. This shows the hallmark of the innate immune response as it is not specific and has no memory to treat pathogens differently. True False
Which of the following is NOT an example of non-specific (innate) resistance mechanisms interacting directly with specific acquired immunity mechanisms? what option below is the answer? Antibodies binding to bacterial surface antigens, coating (opsonizing) the bacteria and enhancing their phagocytosis by leukocytes Macrophages and dendritic cells presenting antigens to lymphocytes None of the other four answers (All are examples of interaction between innate and acquired resistance) Antibody-dependent cell-mediated cytotoxicity Complement being activated by antigen-antibody binding
The classic inflammatory response (heat, swelling, redness, pain) reflects the communication of innate and adaptive defenses. Which of the following is not correct about this response? Group of answer choices Non-cytopathic viruses stimulate the inflammatory response Adjuvants stimulate inflammation and therefore a good antibody response Dendritic cells link the innate and adaptive responses Tumor necrosis factor alpha is a major inducer of inflammation Increased blood flow is one result of inflammation
Antibodies can bind specific antigens on ___, allowing for ___ by phagocytes like ___. Group of answer choices Viruses; opsonization; red blood cells Bacteria; opsonization; macrophages Tumor cells; cell lysis; macrophages Viruses; cell lysis; red blood cells Viruses; cytotoxicity; neutrophils Previous
