Portage Pathophysiology Exam Questions with Correct
Answers
Pathophysiology changes to the body's physiology caused by disease
Physiology function of the body
Health Physical, mental, and social well-being
disorder of system characterized by etiologic agents, signs/symptoms, anatomic
Disease
alterations
the study of the cause of disease
Etiology
- etio meaning cause
, Etiologic factors Congenital conditions and acquired defects
Congenital conditions genetic, environmental, combination
injury, infection, lack of nutrients, lack of oxygen, immunological issues, neoplasia,
acquired defects
irritants
sequence of events at the cellular and tissue level that eventually lead to the
Pathogenesis
disease's development.
Injury, latency period, prodromal period, acute phase, remission, convalescence,
Disease development stages
recoverhy
Injury phase exposure, causative agent
latency period incubation period, asymptomatic
Prodromal period precursor, signs+symptoms are nonspecific
Acute phase stereotypical signs+symptoms
Remission signs+symptoms go away
Convalescence recuperation
Recovery disease is gone
morphology structure or form of cells and tissues
Clinical manifestations include signs, symptoms, symdromes
signs objective (heart beat)
symptoms subjective (pain)
diagnosis process of identifying the disease or disorder based on patient's signs and symptoms
Types of diagnostic tests specificity and sensitivity
identifies those without the disease, (true negative)
specificity diagnostic test
- if positive, it rules IN the disease
finds positive results for people with a disease (true positive)
sensitivity
- negative results tells if the disease can be ruled OUT
epidemiology study of disease occurrence in a population
What examples of patterns that patterns in data such as race, age, lifestyle, correlations to disease
epidemiology examines?
prevalence number of people who have a disease at a particular time
incidence the number of new cases arising during a specific period.
morbidity effects on peoples lives (symptoms such as blindness)
mortality death rate
What are the functions of a cell? growth, maintenance, repair, secretion, contraction, energy production and usage
What are the three main structures in a nucleus, cytoplasm, plasma membrane
cell?
Control center of the cell, regulates intracellular activities
Nucleus
- contains DNA stored in 46 chromosomes in humans
Deoxyribonucleic acid
DNA
- encodes info needed for protein synthesis
What are the three types of RNA and what Messenger RNA, ribosomal RNA, transfer RNA
purpose do they serve? - serve to move to the cytoplasm to carry out protein synthesis
