|
antigens
|
bad foreign particles that generate antibodies
|
|
|
phagocyte
|
cell that engulfs and destroys foreign particles
|
|
|
phagocytosis
|
lysosomes with hydrolytic enzymes move in clump inside antigen to destroy it through lysis
|
|
|
vasoactive agent
|
secretion from basophils and mast cells that change shape of vessels - either dilate or constrict
|
|
|
antagonist to vasoactive agent
|
anti-histamine secreted by eosinophils
|
|
|
allergy
|
hypersentive reaction of body to an allergen
|
|
|
allergen
|
antigen that causes an allergic reaction
|
|
|
anaphylaxis
|
mast cells don't know when to stop and allergic reaction goes to whole body and can kill the person
|
|
|
major basic protein
|
released by eosinophil to protect against nematodes and other parasites
|
|
|
phagosome
|
phagocytic vesicle around a particle that has been engulfed by phagocytosis
|
|
|
lysosome
|
present in granular leukocytes; destroy anything that gets phagocytosed
|
|
|
phagolysosome
|
lysosome moves and fuzes with phagocytic vesicle
|
|
|
hydrolysis
|
process of slamming water to break up the polypeptide bonds of a substance
|
|
|
hydrolytic enzyme
|
in lysosomes, uses hydrolysis to break viruses, etc...
|
|
|
histamine
|
vasoactive agent that dilates blood vessels and constricts airways as a reaction to an allergen
|
|
|
anti-histamine
|
counteracts histamine to moderately reduce allergic reactions
|
|
|
microphage
|
neutrophil
|
|
|
macrophage
|
mature monocyte
|
|
|
monocyte
|
agranular leukocyte recently formed by hemopoetic tissues, will mature in circulatory system to become a macrophage
|
|
|
antibody
|
proteins/amino acids hooked in 4 chains that attack antigens; also called immunoglobulin
|
|
|
immunoglobulin
|
antibody; five types
|
|
|
antigenicity
|
ability to generate antibodies
|
|
|
immunity
|
resistance to antigen; can be natural or artificial, passive or active
|
|
|
antigenic determinant sites
|
the spot on antibody that is specifically designated to bind with specific antigen
|
|
|
vaccination
|
inject antigenic determinant sites so body can form memory cells to fight the actual disease or sickness
|
|
|
immunization
|
body goes through 2 week period to produce memory cells and prevent antigen from affecting body again
|
|
|
active immunity
|
the 2 week process to immunity that naturally takes place in body without help from outside substances
|
|
|
shingles
|
viral disease when chicken pox hides out in neural cells and erupts leading to discomfort mostly in people over 65 years
|
|
|
attenuate
|
to weaken virus so it cannot cause a disease when used in vaccinations
|
|
|
HIV
|
contain antibodies against HIV; human immunodeficiency virus
|
|
|
AIDS
|
acquired immune deficiency syndrome that destroys t-helpers so body can no longer produce antibodies
|
|
|
gammaglobulin
|
portion of plasma with circulating antibodies
|
