Pathophysiology Flashcards
(36 cards)
Pathophysiology
study of functional or physical changes in the body as a result of disease
Epidemiology
science of tracking the pattern or occurrence of disease
gather data to control or manage health problems within populations
Etiology
causative factors of a disease or origin of a condition or abnormality
Hypertrophy
increase in size of normal cells
increase in size of the organ, tissue, or structure
no cell division
Hyperplasia
an abnormal increase in the number of normal cells
increase in the size of the organ, tissue, or structure
excessive somatic cell division increased risk for cancer
Hypoplasia
underdevelopment of an organ, tissue, or structure
Idiopathic
cause of disease is unknown
Oncology
study of malignant tumors
Seeding
spread of neoplastic cells in body fluids or along membranes in cavities
movement of primary tumor with dislodgment and dispersal of tumor cells
Factors influencing disease process in the elderly
psychological
degenerative (organ systems)
decreased immune response
Environmental factors
pollutants (water, chemical, exhaust, noise)
Characteristics of benign tumors
encapsulated
slow-growing
similar to normal cells
rarely recur
Cardinal signs of inflammation
pain
redness (rubor/erythema)
swelling
heat
loss of function
Iatrogenic
a disease, condition, or injury caused by a medical or surgical intervention
Lesion
circumcised area of pathologically altered tissue
microscopic or highly visible
Morbidity
disease rate in a group
functional impairment associated with a specific condition
Neoplasia
abnormal growth of tissue which serves no useful function
grows at the expense of the host
benign or malignant
Why are the elderly prone to infection?
reduced function at cellular/organismal level
can’t adapt to change
poor circulation
lessened healing
impaired immune function
Complication
a disease, condition, or accident which is superimposed on another without being specifically related
effects or modifies prognosis of disease
additional problems that arise
Mortality
number of deaths resulting from a disease
Metaplasia
abnormal conversion of a mature cell type to a different mature cell type
adaptive, provides protection or resistance
Prognosis
prediction of the course and end of a disease and the estimate for a chance of recovery
Signs
objective evidence of a disease or condition (observable)
Symptoms
subjective experiences of a disease or condition (observable to patient only)
