II. Some basic physiologic concepts.
B. Compensation and decompensation
b. Control / compensatory mechanisms examples:
1. Example of compensatory response to normal daily life
stressor concept flow chart map with elevated external
temperature or exercise
1. body temperature rises
the hypothalamus senses the elevated core temperature and
sends a signal to the skin to produce sweat
heat loss occurs through evaporation. Dilation of the superficial
blood vessels also occurs
as "heated blood" circulates from the core to the periphery
heat loss occurs through radiation (heat removed from body
into surrounding air).

2) Example of compensatory response to pathologic stressors if
youve lost a lot of blood
(massive bleeding) or water (dehydration), the body uses
certain compensatory techniques to keep remaining fluid
volume circulating as effectively as possible (temporary
measures until the cause of the problem gets fixed) :
a) heart rate would increased.
b) also, arteries in your periphery (arms and legs) would
constrict, shunting whatever blood volume is left to
the central areas
III. Pathophysiologic concepts & terminology
Precipitating factor?
a. a condition or event that triggers a pathologic event or
disorder ….
the “kick-off”
b. ex—“an asthma attack can be precipitated by exertion”
Iatrogenic vs Nosocomial
Iatrogenic : caused by medical tx
nosocomial : hospital acquired
III. Pathophysiologic concepts & terminology
D. Terms relating to course of a disease
, 4|Page
Prognosis?
predicted outcome of a dz based on certain factors
usual course of dz
Aglia
pain, painful condition
ectomy
suffix denoting removal of an anatomical part
hemorrhage
hemorrhage- escape of blood from the intravascular space. To
bleed.
iasis
iasis—suffix meaning state or condition.
ostomy
suffix meaning artificial opening (stoma) into the urinary or
gastrointestinal tract or trachea
SO2
oxygen saturation (measured as percentage
otomy
suffix meaning a cutting operation
plasty
