Document Summary
Homeostasis: refers to temperature regulation and other biological processes that keep body variables within a fixed range, homeostatic processes in animals trigger physiological and behavioural activities that keep certain variables within a set range. Set point: a single value that the body works to maintain. Negative feedback: processes that reduce discrepancies from the set point. Allostasis: the adaptive way in which the body anticipates needs depending on the situation, and avoiding errors rather than correcting them. Basal metabolism: the energy used to maintain a constant body temperature while at rest. Poikilothermic: body temperature matches the temperature of their environment, amphibians, reptiles, and most fish. Homeothermic: physiological mechanisms to maintain a nearly constant core temperature despite. Brain mechanisms changes in the temperature of the environment: physiological changes that regulate body temperature such as shivering, sweating and changes in blood flow to the skin depend on areas in and near the.
