- Can you create fill-in-blank questions for me about the Immune System. I need 6 questions with the answer tooSecondary lymphoid organs, such as the lymph nodes, spleen, and mucosa-associated lymphoid tissues, each have distinct features that are important for their role in initiating immune responses focused on different anatomical compartments (i.e., the peripheral tissues, the blood, or the gastrointestinal tract, respectively). Yet these organs share some overall structural features, such as distinct T-cell and B-cell zones. One major difference between these organs is: The presence versus the absence of macrophages and dendritic cells Their function in bringing rare naive lymphocytes into contact with their specific antigen The ability of lymphocytes to enter the organ from the blood The mechanism by which antigens or pathogens enter the organ The ability of naïve T cells to be activated and proliferate in the organEileen presents with flu-like symptoms, including fever, chills,and body aches:- a. What part of the immune response is likely producing these symptoms? b. You order blood work and find that the number of neutrophils in the blood is greatly elevated. What does this tell you about the likely type of pathogen involved? Explain. c. What might it mean if lymphocytes instead of neutrophils were elevated? Explain your reasoning
- Why are the axillary lymph nodes often biopsied in cases of suspected breast cancer?Lymphocytes that develop immunocompetence in the thymus are __________lymphocytes. We put everything in our mouth since our childhood. Therefore our mouth is full of live bacteria. These bacteria are potentially dangerous if they cross our gut wall into our blood circulation. Fortunately we are protected from them by our gut's mucosal lining and the cells (macrophages, dendritic cells, B and T lymphocytes) in the lymphoid tissue called [a] (enter two words). This structure play a crucial role for the development of food tolerance or food [b] (enter one word), coeliac disease and chronic inflammatory bowel disease.Match these lymphocytes to their specific functions Cytotoxic T-cells [ Choose ] Aid other types of lymphocytes Part of general immunity Reduce response time to subsequent exposures Produce immunoglobulins - antibodies Physically destroy the cells Helper T-cells Plasma cells [ Choose ] Memory T-cells [Choose] Natural killer cells [Choose]
