Exam Questions and CORRECT Answers
What is thermoregulation? - CORRECT ANSWER body temperature
body process that balances production and heat loss
heat produced - heat loss = body temperature
What is the goal of thermoregulation? - CORRECT 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
too cold or too hot, death can occur
What is homeostasis? - CORRECT ANSWER Maintaining a stable internal environment
What is cellular respiration? - CORRECT 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? - CORRECT
ANSWER body temp drops because no energy is being created meaning no heat
What factors affect heat production? - CORRECT ANSWER basal metabolic rate, muscle
activity, thyroxine output, sympathetic stimulation/stress response, fever
What is basal metabolic rate? - CORRECT 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? - CORRECT
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? - CORRECT ANSWER increased
thyroxine levels release epinephrine, when it is released, it increases vasoconstriction, we
accelerated the cellular metabolic rate, increasing the heat production
What is chemical thermogenesis? - CORRECT ANSWER the stimulation of heat
production in the body through increased cellular metabolism
What is sympathetic stimulation/stress response do to body temperature? - CORRECT
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? - CORRECT 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
Wha are different types of heat loss from the body? - CORRECT ANSWER radiation,
conduction, convection, vaporization
What is radiation? - CORRECT ANSWER the transfer of heat from the surface of an
object without touching
getting hot from the sun's rays (not touching)
dog doesn't touch, waking up sweating because the dog radiates so much heat
What is conduction? - CORRECT ANSWER transfer of heat from one molecule to a
molecule of lower temperature, needing to be touching
tepid (cool) bath
-taking someone with a fever, putting them in a cool bath
ice packs
cool washcloths
, heating pad
What is convection? - CORRECT ANSWER dispersion of heat by the fluid of air or water
across the skin
convection oven has a fan in the back, heat is being dispersed through the fan
heat loss: fan
spritzing water
when dog is radiate heat, turn on fan to bring my body temperature down
fluid motion of air comes down and blows it away
amusement park with mist showers
What is vaporization? - CORRECT ANSWER continuous evaporation of moisture form
repository tract, mucosa of mouth or skin (swat glands)
perspiration when we work out
millions of sweat glands that produce perspiration (sweating), and when the body needs to lose
heat (cool) the sweat glands will sweat and then it will evaporate
when you sweat, body is trying to drop body temperature
How is the heat of the body measured? - CORRECT ANSWER celcius and fahrenheit
