|
Non specific defense, Fever |
Defense initiated by pyrogens from macrophages that cause the hypothalamus to reset the bodies temperature |
|
|
Specific immunity |
APCs present epitopes of what they have sampled from their external environment on MHC proteins. Other cells present internal self antigens |
|
|
Humoral (antibody mediated immunity (specific immunity) |
Primary immune response, the first time you are exposed to the pathogen. The response is slow taking 3 to 6 days for activation and 10 more days for peak antibody production |
|
|
cellular immunity involves |
antigen recognition, costimulation, cloning and differentiation, lethal hit or interleukin secretion for other outcomes, |
|
|
forms of acquired immunity, passive |
immunity acquired through somone or something else |
|
|
active |
body activily reacted its own immunity |
|
|
natural |
immunity accomplished through naturally occuring means |
|
|
artificial |
immunity was not acquired naturally |
|
|
forms of acquired immunity, natural active immunity |
the usual response of being exposed in forming immunity |
|
|
Natural passive immunity |
acquired by a newborn from the mother |
|
|
forms of acquired immunity, artificial active immunity |
vaccinations |
|
|
forms of acquired immunity, artificial passive immunity |
antiserum |
|
|
importance of t helper cells in nonspecific resistance and specific immunity |
t helper cells activate macrophages for nonspecific defense such as infammation and fever. t helper cells recognize what is foreign and release interleukin 2 to activate B cells in humoral immunity. T helper cells recognize what is foreign and release interleukin 1 to activate cytotoxic cells in cellular immunity. |
|
|
functions of the lymphatic system |
the lymphatic system helps maintain the fluid balance in the blood. they lymphatic system distributes lymph to wash over tissues to deliver nutrients and remove wastes. the lymphatic system carries absorbed products of lipid digestion. |
|
|
functios of the lyumphathic system |
the lymphatic system provides nonspecific defenses. they lyph system provides specific immunity against specific pathogens. |
|
|
effects of aging on the lymphatic system |
the ability to move fluid between the cardiovascular and lymphatic systems does not decrease with age. the number of B cells in the lymphoid tissues will remain relatively stables. The thymus gland shrinks with age. the number of new T cells decreases with age. the immune response may slow with age. old viruses may reemerge like shingles. |
|
|
Allergies are |
hypersensitivities to a pathogen that may have immediate or delayed side effects. |
|
|
autoimmune disorders are the results of the |
immune system attacking self antigens. Rheumatoid arthritis, graves disease and myasthenia gravis. Mimicry is one molecule is so similar in structure to another molecule that it is mistaken for the other molecule. |
|
|
aids acquired immunodeficiency syndrome |
final stage of an HIV infection in which the immune system fails to recognize foreign antigens. affects the ability to fight opportunistic infections. kaposi sarcoma. |
|
|
karposi sarcoma is |
a scab looking thing on an HIV or AIDS patient |
