Basic Mechanisms of Pathophysiology Flashcards
is a result of disease and changes in homeostasis
Pathology
Process of maintaining normal balance within the body
Homeostasis
When homeostasis is not maintained, ____ ensues.
Disease
Study of abnormal functions in the body and how diseases processes work
Pathophysiology
The development of the disease
Pathogenesis
-genesis
Origin or development
Sequence of events that leads from cause of disease to structural and functional abnormalities, to how the diseases manifests itself and finally to the resolution or recovery of the disease
Pathogenesis
Common cold cause?
exposure and inoculation of cold virus
Common cold incubation time
virus multiplies
Common cold manifestation
host begins to have signs and symptoms (sore throat, itchy eyes, runny nose, etc.)
Common cold recovery
return to previous state of health
disease of sudden onset which runs a severe but short course
acute disease
long-term (sometimes reoccurring) illness
Chronic
a. ) immature immune system
b) liver enzymes necessary for detoxification
Newborn babies
a. ) decrease in immune function
b. ) decline in homeostatic mechanisms
Elderly
some diseases are more prone to one gender than the other
Sex
familial tendencies for: diabetes, asthma, migraines, etc.
Genetic makeup
increases body’s production of corticosteroids, which decreases immune system function.
Stress
personal habits in regard to diet, exercise, weight control, smoking, alcohol consumption, sexual practice
Lifestyle
exposure to loud noises, pollutants, repetitive movements, heavy equipment, high places, etc.
Occupation
illnesses can lower body’s resistance and make individuals more susceptible to other diseases
Preexisting illnesses
chronic illness interferes with proper function of some body systems, therefore complicating disease
Preexisting illnesses
prolonged exposure to cold or heat can lower the body’s resistance
Environmental exposure
exposure to allergens
Environmental exposure
