Select ways that the immune system may shift away from homeostasis to fight infection. Check All That Apply B cells become many times more abundant than normal. Antibodies divide to produce more antibodies. Cytokines trigger the body to warm up during a fever. Bacteria circulating in the lymphatic system die. Blood vessels widen and become leakier. Infected body cells produce allergens to increase the immune response.

The ability to develop a secondary immune response is based on ______. a. memory cells b. circulating antibodies c. plasma cells d. effector cytotoxic T cells e. mast cells
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.
Cell-mediated responses work best against ________. a. pathogens inside cells b. pathogens outside cells c. toxins d. both b and c e. all are correct
Which of the following is true about the immune system? Check all that apoply. Rejecting organs or bone marrow transplantation is the normal function of the immune system Overreaction of the immune system to cause allergy or causing autoimmune diseases is normal function of the immune system Immune system discriminates between self and non-self Immune system eliminates infectious agents but not cancer from the human body Eliminating infectious agents and cancer are the normal functions of the immune system
Which of the following is true about the innate immune system? Check all that apply Phagocytosis is an adaptive immunity component required for elimination of microbes Innate immune cells are macrophages and dendritic cells that engulf pathogens but also present antigen to T lymphocytes Innate immunity improves with repeated infections Neutrophils are the abundant innate immune cells circulating in blood Innate immune system provides protection immediately after infection in a non-specific manner
Which of the following is true about the adaptive immune system? Check all please. Adaptive immunity develops several days after the initial infection, but eliminate pathogens in a specific manner and is saved as memory to encounter the same reinfection Adaptive immunity is improved with repeated infections with the same pathogen A robust primary adaptive immunity can be generated in the absence of innate immunity Adaptive immune cells are B cells that make antibodies and T cells that eliminate infected cells and make cytokines Dendritic cells present antigens to T cells, whereas macrophages present antigens to B cells.
Which of the following is true about the immune system? Check all that apply. CD4 T Cells kill infection cell efficiently, whereas CD8 T cells only make cytokins Bone marrow and thymus are primary lymphoid organs and spleen and lymph nodes are secondary lymphoid organs Dendritic cells (DC) are the professional antigen presenting cells, whereas macrophages and B cells can present antigen for the second time. Immune response occurs mainly in the secondary lymphoid organs DC present antigens to T cells in the context of MHC, whereas B cells see antigens on their own in native conformational form
Which of the following is true about the immune system? CHeck all that apply. Neutrophils are abundant granulocytes that phagocytose bacteria, whereas eosinophils eliminate helminth parasites Anatomic barriers include epithelial cells, macrophages, dendritic cells Dendritic cells and macrophages are phagocytic cells that can present antigen T lymphocytes Innate immune cells are macrophages, granulocytes, natural killer cells and adaptive immune cells are B and T cells B and T cells originate from myeloid progenitor, whereas monocytes and neutrophils from lymphoid progenitor.
The Immune System Filin the blanks.. Two integrated systems defend our body against immunity disease. The (nonspecific) system responds skin to all types of foreign substances. It includes physical inflammation barriers like and mucous membranes as well as adaptive as fever, and natural killer cells. The innate (specific) system defends against a particular foreign substance. It uses lymphocytes and antibodies DRAG to build long lasting to pathogens. 5 Teamwork Toolbox
Body Systems The human immune system consists of a network of cells, tissues, and organs. The cardiovascular system consists of the heart, blood vessels, and blood. How do the immune and cardiovascular systems work together to protect the human body? OA. The immune cells send electrical signals through the blood to the brain. OB. The two systems allow for the exchange of gases between the blood and the rest of the body. OC. The blood acts as a medium for the transportation of immune cells throughout the body. OD. The two systems allow for the storage of nutrients to fuel the body at a later time. Reset Submit
Which is/are false about innate and specific immunity? B cells are part of the innate immune system T cells activate B cells and cause them to undergo clonal expansion Langerhans cells are specialized to detect pathogens in the skin Eosinophils are part of the innate immune system
Which of these is an incorrect description of either the adaptive or innate immune responses? Innate immunity involves both surface barriers and internal defenses. Only adaptive immunity involves defense against a specific foreign invader. Inflammation is an innate immune response but not an adaptive immune response. Chemicals are involved in adaptive immunity but not innate immunity. Immune system cells play a role in both innate and adaptive immune responses.
