Immune Response Flashcards
(61 cards)
What are the first line of defenses
Skin
mucous membrane
secretions
gastric acid
major histocompatibility complex
What are the cellular defenses
Neutrophils
Basophils
Eosinophils
Monocytes
Respond to a bacterial infection (pyogenic infection), acute
inflammation, heart attack, or burn
Neutrophils
The substances include histamine, heparin, and other chemicals
used in the inflammatory response.
Basophils
Respond to parasitic infection, allergic reaction, cancer
Eosinophils
Remove foreign material from the body, including
pathogens, debris from dead cells, and necrotic tissue from injury sites
Monocytes
is the local reaction of the body to
invasion or injury. Any insult to the body that
injures cells or tissues sets off a series of events
and chemical reactions.
Inflammatory response
Four inflammatory response
a.Kinin System
b.Histamine Release
c.Chemotaxis
d.Clinical Presentation
Five (5) Different Types of Immunoglobulins
IgM
IgA
IgD
IgG
IgE
the first immunoglobulin being released, which contains the
antibodies produced at the first exposure to the antigen.
IgM
another form of immunoglobulin, contains antibodies made by the
memory cells that circulate and enter the tissue; most of the
immunoglobulin found in the serum
IgG
found in tears, saliva, sweat, mucus, and bile. It is secreted by
plasma cells in the GI and respiratory tracts and in epithelial cells. These
antibodies react with specific pathogens that are encountered in exposed
areas of the body.
IgA
present in small amounts and seems to be related to allergic
responses and to the activation of mast cells.
IgE
another identified immunoglobulin whose role has not been
determined.
IgD
Normally released by the adrenal glands
- mimics action of steroid hormone
Corticosteroids
Aldosterone-like actions and balances
electrolytes through Na and water reabsorption.
Mineralocorticoid
regulates CHON, carbo, and fat metabolism;
affects metabolism. Promotes antibodies, does not produce insulin
Glucocorticoids
Addisonian 3 signs
Decreased BP
Cyanosis
Shock
Long term steroid use/rapid cessation
Addisonian disease
Cortisone use
Tiredness and apathy
Cushing’s disease
Cushing’s disease’s vital signs
Increased BP
Decreased RR and PR
Corticosteroids Parenteral
prednisone
dexamethasone
hydrocortisone
betamethasone
Corticosteroids Inhaled
beclomethasone
dexamathesone
Corticosteroids Opthalmic
dexamethasone
flouromethalone (Fl
