Thermal control mechanisms Flashcards
Homeothermy refers to the ability to regulate our ??? temp
internal temp
poikliotherms refers to creatures that do not regulate ???
internal temperature
core body temperature depends on time of day: lowest around 3-6 am or pm?
am
core body temperature depends on physical exercise due to heat ??? due to metabolic activity
generation
TRUE or FALSE: stage of menstrual cycle afects core body temperature
TRUE
rate of heat production is linked to metabolism as heat production is directly proprotional to rate of ??? consumption as fuel (food) is oxidised
O2
metabolic reactions generate heat due to ??? eg shivering skeletal muscles adds to metabolic heat production (need ??? for shivering)
energy waste
ATP
onset of exercise = spike or drop in heat production in proportion to exercise intensity?
spike
during exercise, what is the following process known as? thermoreceptors detect temperature change –> hypothalamus compares and detects error, causing an efferent output = slows rate of heat storage
thermoregulation
