Physiology - Answers✔how an organism accomplishes actions in order to stay alive
purpose - Answers✔"why" an action is happening
mechanism - Answers✔"how" an action is happening
biology, anatomy, chemistry, physics - Answers✔4 things that make up physiology
ATP <--> ADP+Pi+energy; our currency to pay for activities - Answers✔equation 1 and
meaning
glucose+O2+ADP+Pi--> ATP+CO2+H2O+heat; how we make the currency -
Answers✔equation 2 and meaning
no - Answers✔is equation 2 reversible?
CO2+H2O<---> HCO3-+H+; transport a gas in water - Answers✔equation 3 and meaning
more acidic - Answers✔what happens when you add more H+?
PV=nRT; Ideal Gas Law (liquids too), allow us to see relationships of things -
Answers✔equation 4 and meaning
homeostasis - Answers✔relatively stable maintenance of a body parameter
dynamic constancy - Answers✔what is homeostasis also known as?
set point (SP); maintaining 98.6 body temperature - Answers✔goal *range* that you are trying to
maintain through homeostasis; example?
genetics, biorhythms, environment - Answers✔what 3 things influence set point?
steady state (SS) - Answers✔maintaining at the set point
homeostatic control systems - Answers✔interconnected components that work together to keep
the set point and maintain steady state

energy is required to remain at steady state, disturbances (d) from steady state -
Answers✔consequences of homeostatic control systems
reactive-->response=feedback - Answers✔formula for reactive disturbances from SS
negative feedback - Answers✔99% of feedback, opposite of disturbance, goes back towards
steady state
positive feedback - Answers✔continue with disturbance, going away from steady state
feed forward (FF) - Answers✔proactive-->preparation = ____
do things before instead of reacting after; limits the degree of feedback required and less energy
required - Answers✔what is the purpose of feed forward?
reflex template (arc) - Answers✔set up for a response to something that happens - used in the
homeostatic control system
stimulus, x altered, sensor/receptor, (afferent pathway), integrating center, (efferent pathway),
effector(s), compensatory response (change in physiology), x restored - Answers✔steps of reflex
template
detection (internal and external), integration (comparison to SP), adjustments if needed (if at SS
don't need adjustments) - Answers✔keys to reflex template
negative feedback (limits # of times through template), positive feedback (increases # of times
through template), develop feed forward (x is altered less) - Answers✔results of reflex template
biorhythms; temp inc and dec throughout day - Answers✔pattern to the variation of a controlled
variable (parameter); example?
period; circadian, lunar, annual - Answers✔how often the pattern occurs; types
phase - Answers✔how long we can see a spike; occurs in period pattern
amplitude - Answers✔having a high or low amount; peak
proactive (feed forward) - Answers✔accomplished by being ____
adaption; genetic change - Answers✔set up for survival = _____ = ___ ___
acclimatization - Answers✔adjustable (limited) = _____
individual level - Answers✔where do adjustable biorhythms occur
developmental acclimatization - Answers✔what is it called when acclimatization is not
reversible
