chapter 27 terms

an exaggerated hypersensitivity reaction that in severe cases leads to vascular collapse, bronchospasm and shock.

immunoglobulins produced by the immune system in response to bacteria , viruses or other antigenic substances

a foreign substance that causes the production of a specific antibody

substances that inhibit the growth of microorganisms on living tissue

examples: alcohol , and betadine

pertaining to a disturbance in the immune system in which the body reacts against its own tissue

examples: multiple sclerosis, rheumatoid arthritis and lupus

an infection caused by a yeast that typically affects the vaginal mucosa and skin

 to form into clots

soiled with pathogens or infectious material, nosterile

a liquid chemical that is capable of eliminating many or all pathogens but is not effective against bacterial spores

contaminated, nonliving objects that can transmit infectious organisms

agents tht destroy pathogenics organisms

condition , or disease transmitted from parent to offspring on the DNA chain

a protein formed when a cell is exposed to a virus, the protein blocks viral action on the cell and protects against viarl invasion

infections caused by a normally nonpathogenic organism in a host whose resistance has been decreased

a substance that relieves or alleviates the symptoms of a disease without curing the disease

the injection or introductions of substances into the body by any route other thant the digestive tract

examples: subcutaneous, intrvenous, or intramuscular administration

examples: ticks , insects

any sustained harmful alteration of the normal structure , function, or metabolism of an organism or cell

mycotic infections

inflammatory process and immune system response

the immune system responds by producing antibodies specifically designed to combat the presence of a foreign substance or antigen , responsibility of the body's B cells

the immune system reacts at the cellular level with T-cell by causing the destruction of pathogenic cells at the site of invasion.

example: phagocytosis

when trauma occurs to the body or it is exposed to pathogens protective mechanisms are alerted and the body reponds in a predicatable manner

rapid onset of symptoms but lasts a relatively short time

time when th patient first show vague, nonspecific symptoms of disease

long period

without symptoms
