Document Summary

Limited number of systems essential for life so maintained over narrow range. Other systems operate within a wider range and vary to meet perceived/anticipated demands. A change in the set point in a regulatory system. Blood pressure varies around different set points depending on the time of day and activity level. Actively maintains homeostasis around the set point. Ans is a system that varies according to demand. The price the body pays for being forced to adapt to adverse conditions. Inefficient operation of the allostasis response systems. Too large of a change in the set point. You have high blood pressure for so long, body makes it the set point. An event or events interpreted as threatening to an individual (and to homeostasis) and which elicit a stress response. Stress response: collection of physiological and behavioral responses. Activation of the sympathetic branch of the ans. Epi affects glucose metabolism by increasing glucagon.
