Unformatted text preview: 6-1-11: BIPN 102ThermoregulationWaters heat capacity is really high. Water and birdy example. Not a closed system.If bird in closed system, humidity Can be used as a clock, but will change depending on the humidity.Fig 22-18: Energy balance on the bodyEnergy input from diet. Process generate heat and work.Heat from mechanical & chemical processes.Exothermic reactionsUnregulated heat production, basal level. Work involves transport across membranes, mechanical work, chemical work, synthesis and generation of chemical bonds etc.Heat exchange mechanisms.Fo temp to be maintained, ext input from enviro and total heat production must equal heat lossOtherwise temp changeFig 22-19: heat balance in the bodyConductionRadiationConvectionEvaporationHot cold (conduction, radiation, convection)EXAMPLE: WA DCHumidity high, temp 98oF....
