L19-20 Thermal physiology Flashcards
Define Q10, the measure of temperature sensitivity
。。。
Define and explain the differences between the 4 major mechanisms of heat exchange in a vertebrate
。。。
Define the components that comprise the total heat content of a vertebrate. Explain the formula fo the calculation of body heat
、
Define and know the physical isolation of, the vertebrate thermostat. Understand the process of fever and how this relates to regulation of body temperature.
。
Explain the difference between a homeothermic animal and a poikilothermic animal. Justify why these classifications are sometimes inappropriate when describing the thermal biology of the vertebrate.
、
Describe the basis for the term ‘heterotherm’，and be able to describe the hear relationship of a regional heterotherm and a temporal heterotherm.
。
Explain the process of countercurrent heat exchange.
。
Explain why water is an effective means of heat dispersion.
。
Explain the thermo-physiological differences between an endothermic animal and an ectothermic animal.
。
Be able to provide an example of body temperature regulation of an ectotherm
。
Provide examples of adaptations for endotherms living in a cold or a hot environment
。
Define what is meant by the critical thermal maximum in ectotherms
。
Define the terms thermoneutral zone, lower critical temperature (LCT) and upper critical temperature (UCT)
。
Explain and justify the changes that occur in endotherm metabolic rate and body temperature when temp go below the LCT or above UCT.
。
Describe two major physiological processes that occur to increase hear production in cold environments for endothermic vertebrate.
