HOSA pathophysiology chapter 1
Questions and All Actual Answers
2025-2026 Updated.
Health - Answer The condition in which the human body performs its vital functions
normally
Homeostasis - Answer Relatively stable internal conditions under fluctuating environmental
conditions
Disease - Answer A deviation from normal structure or function in the body that interrupts
or modifies the performance of vital functions
Pathology - Answer The study of disease, especially the structural and functional changes
associated with disease
Pathologist - Answer A physician who studies and interprets the changes caused by disease
Signs - Answer Evidence of disease observed on physical examination
Symptoms - Answer Indications of disease reported by the patient
Asymptomatic - Answer No signs or symptoms
Syndrome - Answer An abnormal structure or function characterized by a group of signs and
symptoms that usually occur together
Disorder - Answer A functional abnormality not necessarily linked to a specific cause or
physical abnormality
Diagnosis - Answer The process of identifying a disease or disorder
Inspection - Answer A visual examination of the external surface of the body, its movements,
and posture for abnormalities or evidence of disease
Palpation - Answer Feeling the body with fingers or hands, allows examination of the size,
consistency, texture, location, and tenderness of an organ or body part
, Auscultation - Answer Listening to the lungs, heart, and intestines, allows evaluation of the
frequency, intensity, duration, number, and quality of sounds originating in the body
Percussion - Answer Producing sounds by tapping on specific areas of the body with fingers,
hands, or a small instrument, allows evaluation of the size, consistency, and borders of the body
organs, and the presence of absence of fluid in body areas
Vital signs - Answer (pulse, respiratory rate, blood pressure, temperature) are measures of
various physiological statistics in order to assess the most basic body functions.
Biopsy - Answer Surgical removal and analysis of tissue samples, yields information about
changes at the cellular level
Electrocardiography - Answer Reads the heart's electrical impulses
Radiography - Answer Uses x-rays to visualize internal structures
computed tomography (CT) scan - Answer Uses computers and x-rays to create three-
dimensional images of internal structures
magnetic resonance imaging (MRI) - Answer Analyzes tissue responses to a strong magnetic
field to create images of internal structures
Ultrasound - Answer Analyses the interaction of low frequency sound waves with tissues to
create moving images of internal organs
Nuclear medicine - Answer Uses radioactive materials to create contrast in the body and
help form images of the structure and function of organs
Prognosis - Answer Predicted course and outcome of disease
Acute - Answer Sudden onset and short duration
Terminal - Answer Disease that ends with death
Chronic - Answer Slower, less severe onset and a long duration of months or years
