ANSWERS PASS 100%
1. Definition of Pathophysiology: defined as not only the cellular
and organ changes that occur with disease, but also the ettects that
these changes have on total body function.
2. 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
3. 2 types of risk factors: congenital factors (present at birth) or
acquired (occurring after birth)
4. 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)
5. 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.
6. 3 important processes when coming to a diagnosis?:
Patient history, physical examina-tion, and diagnostic tests.
7. 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.
8. 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.
9. Difference between incidence and prevalence:
Incidence - the number of new cases in a population
