FUNDAMENTALS OF HUMAN
PHYSIOLOGY EXAM 1 UIOWA EXAM
QUESTIONS WITH VERIFIED
ANSWERS
, Physiology - ANSWERSStudy of human function
Homeostasis - ANSWERSMaintaining a stable internal environment to support optimal
function under given circumstances
regulated variables of homeostasis - ANSWERSBlood pressure, pH, body temperature,
blood sugar
Set point - ANSWERSvalue where we keep regulation in homeostasis
sensors (homeostasis) - ANSWERSdetect changes in variables and relays to integrator
Integrator (homeostasis) - ANSWERSMakes decision what to do to regulate variables
effectors (homeostasis) - ANSWERSany organ or tissue that receives information from
the integrating center and acts to bring about the changes needed to maintain
homeostasis
Negative feedback system - ANSWERSa process that results in a response that
reverses the original stimulus
Positive feedback system - ANSWERSstrengthens or reinforces a change in one of the
body's controlled conditions (not as common)
feedforward control - ANSWERSThe anticipation of stimuli, activates effectors in
advance (think sprinter before race, body starts to make changes to prepare for event)
levels of organization in the body - ANSWERSatomic
cell
tissue
organ
organ system
organism
Atomic/Molecular Level - ANSWERSall higher level functions are based upon the
principles of physics and chemistry
cellular level of organization - ANSWERSbasic unit of structure and function of living
things
tissue level of organization - ANSWERSgroups of similar cells that have a common
function
