IMMUNOLOGY TEST 1 Immune System With 100% Correct Answers

IMMUNOLOGY TEST 1 Immune System With 100% Correct Answers process of being protected against foreign antigens immunity aka immunoglobins, these are specific glycoproteins found in serum or plasma produced by B-lymphs when body detects harmful substances called antigens antibodies aka immunogens, these large molecules found on surface of cells, viruses, fungi, bacteria, pollen, chemicals, foreign particles causing body to produce antibodies against it; can be formed in the body with bacterial toxins or tissue cells antigens portions or fragments of an antigen that REACT with antibodies and lymph receptors epitope very small molecules that can bind to a larger carrier molecule and behave as an antigen hapten molecule that when coupled with a hapten, renders the hapten immunogenic carrier main function is to recognize microbes as being either self or nonself immune system defense, homeostasis, surveillance 3 functions of immune system first line of defense, natural (innate) immunity, acquired (adaptive) immunity 3 types of immune response defense mechanism that body uses immediately after exposure to a microbe; it is non-specific and nonadaptive natural immunity components include phagocytic cells along with mast cells, neutros and macrophages cellular component components include complement proteins, lysozymes, interferons humoral components proteins that produce inflammatory effects and destroy cells when activated complement proteins enzyme secreted by macrophages that attack cell walls of some bacteria lysozymes proteins produced by many cells in response to viral infections to BLOCK replication of virus in other cells interferons immunity that becomes operational when natural immunity is overwhelmed; it is antigen-specific adaptive immunity (acquired) results in production of antibodies to combat non-self antigens humoral response involves activation of specific lymphocytic cells to combat non-self antigens cell-mediated reponse intitial response for removal of microbes; innate or immunity we are born with; nonantigen specific; nonadaptive; includes mast cells, neutros, macrophages; humoral components include complement proteins, lysozymes and interferons natural immunity secondary defense mechanism; acquired thru life; antigen specific; adaptive; cellular components include antigen presenting cells, macrophages, T-lymphs, B-lymphs; humoral components include antibodies, cytokines adaptive immunity includes bone marrow where T-lymphs and B-lymphs are produced and the thymus found near trachea where stem cells develop into T-cells primary lymphoid organs include mucosa-associated lymphoid tissue (MALT), lymph nodes, and spleen secondary lymphoid organs and tissues composed of small concentrations of lymphoid tissue and provide 1st line of defense against orally ingested pathogens MALT (mucosa-associated lymphoid tissue) bundles of tissue found throughout human body filled with lymphocyte cells that act as filters by removing microorganisms from circulation; part of secondary organs lymph nodes largest of the secondary organs that acts as a filter by trapping and removing foreign materials out the the blood and removes old/damaged RBCs spleen
