Which of the following statements are accurate?OT cells, B cells, and Natural killer cells are Lymphocytes.Once activated, B cells can make clones. Some of these clones are called'memory' cells and will live for years (decades, even) within the body.If you remove the thymus of a baby, you will likely greatly reduce the ability toform mature T cells.T and B cells are considered part of the adaptive immune system.Antibodies and immunoglobulins are the same thing.none of the answers are correct Which of the following are correct?none of the statements are correctLack of iodine in one's diet might cause a disruption in Thyroid hormone levels.As you are under stress while taking this exam, it is possible that the adrenalglands are promoting the synthesis of glucose from non-carbohydrate sources.The steroid hormone known as cortisol would help the body do this.If a person loses too much water in their urine in a short period of time they willlikely die from dehydration. The posterior pituitary hormone, ADH, acts toconserve water in the body.Low levels of TSH might be the cause of hypothyroidism in a patient.If I remove a patient's adrenal gland, it is likely that the levels of ACTH wouldincrease.

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
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 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 regarding Gram negative bacteria? a- Their cell wall is composed of a large proportion of sugars b- Their cell wall does not absorb the Gram stain and turns pink c- Their cell wall is composed of a small proportion of peptidoglycan d- Two of the above statements are true Which T-lymphocytes activate the B-cell response? 1- suppressor T-cells. 2- cytotoxic T-cells. 3- helper T-cells. 4- memory T-cells. Substances that are injected containing an antigen to stimulate the immune system to respond are called a- antibodies b- medications. c- vaccines d- antibiotics
Which of the following statement is TRUE about effector cells? (Select all that apply) Effector cells are created once adaptive immune cells are activated B cell effector cells are called plasma cells T cell effector cells are called memory cells T cell effector cells are the same, regardless of surface cell receptor Each immune response cell has its own effector cell Effector cells arise from differentiation
What is the difference between memory T cells and cytotoxic T cells? Memory T cells need more regulatory cell interactions to become active. Cytotoxic T cells live longer. Memory T cells do not need to interact with antigen-presenting cells to become activated. More cytotoxic T cells than memory T cells are activated during a second exposure to an antigen.
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.
