What is thermoregulation? - ....ANSWER.....✓✓body
temperature
body process that balances production and heat loss
heat produced - heat loss = body temperature
What is the goal of thermoregulation? -
....ANSWER.....✓✓to maintain the body's temperature
within acceptable/safe range
the body wants to maintain homeostasis
body knows where it wants to live (temp. wise), doing
what it can to get back to homeostasis
to prevent death
,2|Page
too cold or too hot, death can occur
What is homeostasis? - ....ANSWER.....✓✓Maintaining a
stable internal environment
What is cellular respiration? - ....ANSWER.....✓✓glucose
and oxygen make energy, with the by product of heat
anything that we do to speed up this process, create
more heat
expend more energy, expend heat
In regards to body temperature, what happens to a
body after a person dies? - ....ANSWER.....✓✓body temp
drops because no energy is being created meaning no
heat
What factors affect heat production? -
....ANSWER.....✓✓basal metabolic rate, muscle activity,
thyroxine output, sympathetic stimulation/stress
response, fever
,3|Page
What is basal metabolic rate? - ....ANSWER.....✓✓the
rate of energy utilization the body uses to maintain
essential activities
decreases with age: metabolism is slowing down
making older people colder
What does muscle activity (exercise) do to body
temperature? - ....ANSWER.....✓✓when you exercise,
you get hot
exercise increases the need for energy (ATP), thus
produces byproduct of more heat
shivering when cold, produces energy, producing more
heat
What does thyroxine output do to body temperature? -
....ANSWER.....✓✓increased thyroxine levels release
epinephrine, when it is released, it increases
vasoconstriction, we accelerated the cellular metabolic
rate, increasing the heat production
, 4|Page
What is chemical thermogenesis? - ....ANSWER.....✓✓the
stimulation of heat production in the body through
increased cellular metabolism
What is sympathetic stimulation/stress response do to
body temperature? - ....ANSWER.....✓✓fight or flight
response
walking into exams, anxious or see a question that
sends you into fight or flight, you get a rush of heat
through body
release of epinephrine and noro-epinephrine, which
will increase metabolism, creating more heat
What does a fever do to body temperature? -
....ANSWER.....✓✓an immune response that raises the
body temperature
not will it raise body temperature, but increase our
metabolic needs/rate, increasing energy and thus our
by product, heat
