Term | Definition |
acid | present in skin and vaginal secretions that inhibit bacterial growth |
acute hypersensitivity | flood of histamines when IgE combines to mast cells |
allergens | antigen produces abnormal response |
allograft | tissue graft from unrelated person |
antibody | protein produced by B cells and attaches to antigens |
antigen | foreign substance, large molecule no normal in body,provoking response |
artificially acquired active immunity | vaccine |
autograft | tissue graft from a different place on one's own body |
chemotaxis | attraction of phagocytes and WBC to area as result of inflammatory chemicals |
cilia | sweep dusty mucus toward mouth to prevent it from getting to the lungs |
complement | lysis microorganisms, enhances phagocytosis by opsonization |
fever | systemic response caused by pyrogens |
gastric juice | hydrochloric acid and protein enzymes, destroys things |
hilus | indented region of lymph node |
histamine | inflammatory chemical that increases capillary permeability causing swelling |
humoral immunity | provided by antibodies present in body fluid |
IgA | baths and protects mucosa |
IgE | triggers histamine, allergic responses, binds to mast cells and basophils |
IgG | most abundant, only type that crosses placenta barrier |
interferon | alerts other non infected cells of invaders, proteins released by viral infected cells |
lymph node | protects body by removing foreign material, bacteria and tumor cells |
lymph capillary | microscopic, blind-ended, absorb leaked fluid |
lymphokine | chemical released by sensitized T cells |
MALT | tissue acts as sentinel (guard) to protect upper respiratory system and digestive tract |
medulla | central region of lymph node, contains macrophages |
memory cell | cell generated during primary immune response and remains in body for long time |
monokine | chemical such as interlukinI or tumornecrosis factor, produced by macrophages |
mucus | sticky substance that traps particles in respiratory and digestive tract |
natural killer cells | contains lysozymes, destroys bacteria |
naturally acquired active immunity | forms mechanical barrier to prevent pathogens |
naturally acquired passive immunity | passed from mother to fetus via placenta, also in milk |
opsonization | cell membranes of become sticky, easier to phagocytize |
peyers pathces | structures that capture and destroy bacteria to prevent from penetrating intestine |
phagocyte | cell that engulfs and destroys |
plasma cell | cell that produces antibodies |
pus | mixture of dead or dying neutrophils, broken tissue cells, and pathogens |
pyrogen | chemical secreted by WBC and macrophages causing the body temperature to rise |
right lymphatic vessel | drains lymph from right arm and right side of head and thorax |
sinus | dilated channel for lymph |
spleen | blood resivour |
suppressor T cell | cells that slow or stop activity of B or T cells |
thymus | produces hormone (thymosin) and functions in immunity |
tonsil | traps bacteria of pharynx |
trabeculae | extensions of capsule extend inward and divide the node into compartments |
afferent lymph vessel | carries lymph into nodes |
