Term
the body's defense system against disease
Definition
immune system
Term
specialized fluid that is formed in the tissue spaces that returns excess fluids and protein molecules to the blood
Definition
lymph
Term
vessels that carry lymph to its eventual return to the circulatory system
Definition
lymphatic vessels
Term
fluid located in the microscopic spaces between the cells
Definition
interstitial fluids
Term
tiny, blind-ended tubes distributed in the tissue spaces
Definition
lymphatic capillaries
Term
terminal vessel into which lymphatic vessels empty lymp; the duct then empties the lymph into the circulatory system
Definition
lymphatic duct
Term
short vessel into which lymphatic vessels from the right upper quadrant of the body empty lymph; the duct then empties lymph into the circulatory system at the right subclavian vein
Definition
right lymphatic duct
Term
largest lymphatic vessel in the body
Definition
thoracic duct
Term
an enlarged pouch on the thoracic duct that serves as a storage area for lymph moving towards its point of entry into the venous system
Definition
cisterna chyli
Term
performs biological filtration of lymph on its way to the circulatory system
Definition
lymph nodes
Term
small lymphatic vessels that carry lymphatic fluid towards the lymph node
Definition
afferent
Term
return of an organ to its normal size after an enlargement; also retrograde or degenerative change
Definition
involution
Term
masses of lymphoid tissue; protect against bacteria, each side of throat
Definition
palatine tonsils
Term
lymphoid tissue; bacteria prtoection; base of tongue
Definition
linguinal tonsils
Term
tonsil near posterior opening of the nasal cavity
Definition
pharyngeal
Term
largest lymphoid organ; filters blood, destrys worn out rbcs, salvages iron from hemoglobin, and serves as a blood resevoir
Definition
spleen
Term
surgical removal of spleen
Definition
splenectomy
Term
hypersensitivity of the immune system to relatively harmelss environmental antigens
Definition
allergy
Term
shock resulting from a severe allergic reaction; may be fatal
Definition
anaphylactic shock
Term
the protective mechanisms that provide immediate, generic protection against any bacteria, toxin, or other injurious particle; also called innate immunity
Definition
nonspecific immunity
Term
nonspecific immune response produced in response to injury resulting in redness, pain, heat, and swelling and promoting moevement of wbcs to the affected area
Definition
inflammatory response
Term
the protective mechanisms that provide specific protection against certain type s of bacteria or toxins; adaptive immunity
Definition
specific immunity
Term
deliberate artificial exposure to disease to produce acquired immunity
Definition
immunization
Term
antigen binding sites, antigen receptor regions on antibody molecule; shape of a specific antigen
Definition
combining sites
Term
immunity that is produced when antibodies mae antirgens unable to harm the body
Definition
antibody mediated immunity
Term
rapid fire series of chemical reactions involving proteins called complements which are triggered by certain antigen reactions and result in the formation of tiny protein rings that create holes in a foreighn cell and thus cause its destruction
Definition
complement cascade
Term
any of several inactive enymes normally present in blood which when activated kill foreign cells by disolving them
Definition
complement
Term
specific antibody produced from a population of identical cells
Definition
monoclonal antibody
Term
fused or hybrid cells that continue to produces the same antibody as the original lymphocyte
Definition
hybridomas
Term
macrophage found in spaces between the liver cells
Definition
kupffer's cells
Term
macrophages that ingest particular matter in teh small air sacs of the lungs
Definition
dust cells
Term
small proteins produced by the immune system that inhibits virus multiplication
Definition
interferon
Term
any of a family of many identical cells descended from a single parent cell
Definition
clone
Term
cell that remains in reserve in the lymph nodes until its ability to secrete antibodies is needed
Definition
memory cell
Term
cells that secrete copious amounts of antibody into the blood
Definition
plasma cells
