Physiological heat losses and their metabolic compensation. Flashcards
Name four means that can cause heat loss?
convection, radiation, evaporation and conduction.
Which parametres does heat loss depend on?
temperature of environment
air flow
humidity
body isolation
What can be used for a physical simulation of heAT LOSS?
Katathermometer
What is the katathermomenter based on?
cooling of subjects by alterations in heat flow density (HFD)
What happens to the heat production of an animal in a cold environment?
It increase because of higher heat-loss compensation
Why has a thermal environment substantial influence on the enegy metabolism especially in young animals?
Because their insulation is not yet fully developed.
Heat loss which cannot be compensated for can cause?
Hypothermia
What is average EE expressed as?
20kJ (4,85kcal)
What is EDK measurement?
a suitable method for evaluation of thermal environment, also enables prediction of heat loss.
