Heat Loss Aim The aim of the investigation is to investigate the nature of heat loss in the human body. This will be achieved by looking at the theory of Homeostasis, followed by conducting an experiment in relation to heat loss. * To determine the relationship between heat loss and body size. * To see if there is any correlation between heat loss, body size and insulation. The Nature Of Heat Loss Many processes both physical and biological are affected by body temperature. Enzymes work rapidly at optimum temperature (37 C) if the temperature alters they may become denatured. Cell membranes become more fragile as temperature rises. Diffusion rates increase by higher temperatures and decrease by lower temperatures. Liquids such as blood become more viscous as the temperature of the body falls. Most animals control their body temperature. Some are Ectotherms (outside heat), meaning they control their body temperature by their behaviour - a...
