-Primary lymphoid organs Red bone marrow (B cell) , Thymus (where T cell mature) -Secondary lymphoid organs Nodes, spleen, MALT (mucosa-associated lymphatic tissue)-tonsil, peyer’s patches, appendix, diffuse lymphoid tissue What is lymphedema? lymphatic blockage- swell Differences between lymph nodes swollen due to disease, such as a viral infection, and those swollen due to cancer. Chapter 21 - The Immune System68.Functions of the immune system. What are some common pathogens our bodies fight? 69.Know the overview of immune system – to understand the relationships between innate immunity and adaptive immunity -Which one is faster, which one is quicker? innate -Which one is generic, which one is specific? adaptive -Which one employs first and second line of defense? innate -Which one employs third line of defense? adaptive -Components of innate immunity - first line and second line of defense (overview only) -Role of inflammation in containing infection (overview only) -Cells involved in adaptive immunity (just know the big picture – We did a lot of detail in exam 3) -Definition of pyrogens fever (which line of defense is it? second line defense) which structure of the body regulates body temperature? _____________________ -Definitions of antigen, antibody, apoptosis antigens are substances that can mobilize adaptive defenses and provoke an immune response 70.Relationship between B lymphocytes, plasma cells, memory cells, Helper T cells, antibodies B cells are activated when antigens bind to surface receptors --> triggers clonal selection --> most clone cells become plasma cells (antibody-secreting effector cells) --> clone cells that do not become plasma cells become memory cells B lymphocytes present antigens to helper T cell to assist their own activation 71.Importance of vaccination, antibodies received from mom; vaccination- active artificially acquired; antibodies from mom- passive and naturally acquired 72.Antibodies – definition and how many types? 73.What is immunological memory (what is made)? Difference between primary immune response and secondary immune response – which response is stronger and faster? cell proliferation and differentiation upon exposure to antigen for the first time (3-6 days) Secondary: re-exposure to same antigen gives faster, prolonged, more effective response (immunological memory) Homeostatic imbalances – Review these (repeat from exam 3, some students had difficulty)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
