BIOD 331 Module 1 Problem Set-Questions and
Answers 100% Correct
Definition of Pathophysiology
defined as not only the cellular and organ changes that occur with disease, but also the effects
that these changes have on total body function.
5 etiologic factors and an example of each
Biological: bacteria and viruses
Physical: trauma, burns, and radiation
Chemical: poisons, drugs
One's genetic inheritance
Nutritional excesses or deficiencies
2 types of risk factors
congenital factors (present at birth) or acquired (occurring after birth)
Difference between morphology and histology
Morphology - fundamental structure or form of cells or tissues (includes the gross and
microscopic changes)
Histology - study of the cells and extracellular matrix of body tissues (at the tissue level)
Signs and symptoms
Signs - objective and can be seen or measured. Elevated temp, leg edema, and changes in pupil
size.
symptoms - subjective. pain, trouble breathing, dizziness.
3 important processes when coming to a diagnosis?
Patient history, physical examination, and diagnostic tests.
Validity, reliability, sensitivity, and specificity definitions.
, Validity - how a tool measure what it is intended to measure.
Reliability - likelihood the same result occurring with multiple testing.
Sensitivity - the proportion of people with a disease who are positive for that disease.
Specificity - are people without the disease who are negative on a given test.
Define epidemiology and name some thing that it tracks.
Epidemiology is the study of disease occurrence in human populations. It tracks, age, race,
dietary habits, lifestyle, or geographic location.
Difference between incidence and prevalence
Incidence - the number of new cases in a population
Prevalence - the number of people with the disease in a population in a given time
Define Mortality and Morbidity
Mortality - the statistics that deal with cause of death in a population
Morbidity is the effect of illness on one's life.
Define Primary, secondary, and tertiary prevention and give an example of each.
Primary: remove risk factors to prevent disease from occurring. Examples - yearly check up,
daily vitamin, vaccination, wearing seatbelts or helmets.
Secondary: detect and treat disease early, usually while the disease is asymptomatic and
curable. Example - pap smears, checking bp and cholesterol and colonoscopy screening. Usually
all done by setting of a physician.
