immune system structures, phagocytosis, innate immunity, humoral immunity, cellular immunity, immunity, inflammatory response, acquired, adaptive, immunity, immune response is how body recognizes, defends against bacteria, viruses, substances that appear foreign, harmful, immune system protects the body from potentially harmful substances by recognizing, responding to so-called antigens, antigens, large molecules, proteins, on the surface of cells, viruses, fungi, bacteria, non-living substances toxins, chemicals, drugs, foreign particles, splinter, antigens, substances that contain these antigens, recognized, destroyed by the immune system, own body cells have proteins, antigens, group of antigens, hla antigens, immune system learns, antigens, does not, react against them, barriers and innate immunity, immune system includes barriers that keep harmful materials from entering body, barriers, part of innate, from birth, immunity, form the first line of defense, in the immune response, of these barriers, the skin, stomach acid, mucus, traps bacteria, small particles, cough reflex, enzymes in tears, skin oils, an antigen gets past the external barriers, attacked, destroyed by other parts, the immune system, blood components, immune system includes certain types of white blood cells, includes chemicals, proteins, in the blood, complement proteins, interferon, of these directly attack foreign substances, others work together to help the immune system cells, inflammation, inflammatory response, inflammation, occurs, tissues, injured by bacteria, trauma, toxins, heat, chemicals, histamine, bradykinin, serotonin, released by damaged tissue, chemicals cause blood vessels to leak fluid, tissues, causing swelling, helps isolate the foreign substance from further contact, body tissues, chemicals also attract white blood cells that "eat" microorganisms, dead, damaged cells, process, white blood cells surround, engulf, destroy foreign substances, phagocytosis, cells, phagocytes, phagocytes eventually die, pus is formed, a collection of dead tissue, dead bacteria, live, dead phagocytes, acquired immunity, acquired immunity, the body is exposed to various antigens, builds a defense that is specific to that antigen, lymphocytes, a special type of white blood cell, b lymphocytes, b cells, produce antibodies, antibodies attach to a specific antigen, make it easier, the phagocytes to destroy the antigen, t lymphocytes, t cells, attack antigens, provide control, the immune response, b cells, t cells develop, specific, one antigen type, exposed to a different antigen, different b cells, t cells, formed, lymphocytes develop, learn to recognize the body's own tissues, self, different from tissues, particles not, found in body, non-self, once b cells, t cells, formed, a few of those cells, multiply, provide "memory", the immune system, allows the immune system to respond faster, efficiently the next time, exposed, same antigen, in many cases, prevent from getting sick, an individual who has had chickenpox is immune to getting chickenpox again, passive immunity, passive immunity involves antibodies, produced in someone's body other than own, infants have passive immunity, born, antibodies, transferred, the placenta, mother, antibodies disappear between 6, 12 months of age, gamma globulin is another form of getting passive immunity that is given by a doctor, its protection is also temporary, immune system disorders and allergies, immune system disorders occur, the immune response is inappropriate, excessive, lacking, allergies involve an immune response to a substance, majority of people, body perceives, harmless, transplant rejection involves, destruction of transplanted tissues, organs, major complication of organ transplantation, blood transfusion reaction, problem, receiving blood, autoimmune disorders, systemic lupus erythematosus, rheumatoid arthritis, the immune system acts to destroy normal body tissues, immunodeficiency disorders, inherited immunodeficiency, aids, occur, failure in, the immune system, signs of inflammation, redness, in the area, pain, in the area, swelling, the affected area, warmth, the affected area, pus, in many cases, no noticeable symptoms, additional symptoms, fever, general discomfort, uneasiness, ill feeling, malaise, muscle aches, agitation, confusion, an infection, a complete blood count, cbc, shows increased numbers of white blood cells, a blood differential count, reveal an high percentage of phagocytes, white blood cells that eat other cells, meaning that the body is responding to a need to fight infection, a problem is suspected, tests performed, complement levels, levels of specific immunoglobulins, antibodies, therapies, action, the immune response is desired, suppression, the immune system, in the treatment of autoimmune disorders, allergies, accomplished by administering corticosteroids, immunosuppressive medications, suppression, the immune system an undesired side-effect of certain treatments, disorders, vaccination, immunization, way to trigger the immune response, small doses of an antigen, dead, weakened live viruses, given to activate immune system "memory", activated b lymphocytes, sensitized t lymphocytes, memory allows body to react quickly, efficiently to future exposures, noted, exposed to a microorganism, destroyed, cause illness, passive immunization involves transfusion of antiserum, contains antibodies, formed by another person, animal, provides immediate protection against an antigen, does not provide long-lasting protection, gamma globulin, equine, horse, tetanus antitoxin, examples of passive immunization, complications, an efficient immune response protects against many diseases, disorders, inefficient immune response allows diseases to develop, inadequate, inappropriate, excessive immune response causes, immune system disorders, complications related to altered immune response, disease development, allergy, hypersensitivity, anaphylaxis, autoimmune disorders, blood transfusion reaction, immunodeficiency disorders, serum sickness, transplant rejection, graft versus host disease.
