Dana De Guzman Pd 3 immune system
Major functions of the lymphatic and immune system
Location of lymphatic organs and their functions
Purpose and examples of first, second and third line of defense
First line:
skin and mucous
Second line:
chemical barriers (pH, enzymes, salf, infernos, complement), natural killer cells, inflammation, phagocytosis, fever
Third line:
Cellular immune response, humoral immune response
Innate (natural) immune defenses and adaptive (aquired) immune defenses
Humoral response and cellular response
Humoral response:
antibodies travel through the body fluids to attack and destroy antigens
Antigens and antibodies
Antigen:
triggers "
non-self" molecules
, which are usually large and complex foreign molecules
Artificial vs. naturally acquired immunity
Naturally immunity:
obtained through antigen exposure; an immune response occurs in the person, in which antibodies and memory B cells are produced; this is long-lasting immunity
Naturally acquired active immunity:
occurs after exposure to the antigen; long-term resistance, results, due to the events of a primary immune response (memory B cells are produced)
Naturally acquired passive immunity:
occurs as antibodies are passed from mother to fetus; this is short-term immunity, due to lack of an immune response and lack of memory B cell formation
Passive immunity:
obtained by receiving antibodies; since there is no antigen contact and no immune response occurs, no memory B cells are produced; this is short-term immunity
Artificially acquired active immunity:
involves vaccine of the weakened pathogen. this forces B cells to remember the pathogen. this is long-term
Artificially acquired passive immunity:
involves the injection of gamma globulins containing antibodies or antiserum; this is short-term, because there was no antigen exposure, no immune response, and no memory cells produced
