Pathophysiology [ Ans: ] The study of the cellular and organ
changes that occur with disease and the effects that these
changes have on total body function
Reliability [ Ans: ] multiple observations of a test give the same
results
© 2025 Assignment Expert
Validity [ Ans: ] the test measures what it is supposed to measure
Sensitivity [ Ans: ] true positive
Specificity [ Ans: ] true negative
Guru01 - Stuvia
Disease [ Ans: ] an acute or chronic illness that one acquires or is
born with that causes physiological dysfunction in one or more
body system
Primary Prevention [ Ans: ] removing risk factors so the disease
does not occur (immunizations)
Secondar Prevention [ Ans: ] detecting disease when still curable
(Pap smears)
Tertiary Prevention [ Ans: ] preventing further deterioration or
reducing complications of disease (antibiotic use)
Homeostasis [ Ans: ] the purposeful maintenance of stable
internal environment
Negative Feedback System [ Ans: ] generates stability; when
functions decrease below set point, feedback mechanisms cause
the functions or values to increase towards normal; when
functions increase above set point, feedback mechanisms cause
functions to decrease towards normal
Positive Feedback System [ Ans: ] least common feedback
system in the human body; generates instability within the system;

example: oxytocin during labor to cause uterine contractions and
cervical dilation
Acute Stress [ Ans: ] lasting less than 4 weeks
Chronic Stress [ Ans: ] lasting 1-6 months plus
Post-Traumatic Stress [ Ans: ] chronic activation of the stress
response as a result of experiencing a potentially life-threatening
event
Nervous System Mediating Stress Response [ Ans: ] In the nervous
system, stress triggers the sympathetic nervous system, prompting
the adrenal glands to release catecholamines. Once the acute
stress-induced crisis subsides, the parasympathetic nervous system

aids in the body's recovery
Sleye's Definition of Stress [ Ans: ] a state manifested by a
specific syndrome of the body developed in response to any

stimuli that made an intense systemic demand on it
Stages of Stress [ Ans: ] 1. Alarm stage- release of
catecholamines and cortisol (fight or flight)
2. Resistance Stage- body selects the most effective and
economic channels of defense
3. Exhaustion Stage- resources are depleted
ANS Stress Response [ Ans: ] The autonomic nervous system has a
direct role in physical response to stress and is divided into the
sympathetic nervous system (SNS), and the parasympathetic
nervous system (PNS). When the body is stressed, the SNS
contributes to what is known as the "fight or flight" response.
Endocrine Stress Response [ Ans: ] Reactions to stress are
associated with enhanced secretion of a number of hormones
including glucocorticoids, catecholamines, growth hormone and
prolactin, the effect of which is to increase mobilization of energy
sources and adapt the individual to its new circumstance.
Immune Stress Response [ Ans: ] - Stress stimuli: increases
corticosteroids
