<P> Homeostatic imbalances are the main driving force for changes of the body . These stimuli are monitored closely by receptors and sensors in different parts of the body . These sensors are mechanoreceptors , chemoreceptors and thermoreceptors that , respectively , respond to pressure or stretching , chemical changes , or temperature changes . Examples of mechanoreceptors include baroreceptors which detect changes in blood pressure , Merkel 's discs which detect sustained touch and pressure , and hair cells which detect sound stimuli . Homeostatic imbalances that can serve as internal stimuli include nutrient and ion levels in the blood , oxygen levels , and water levels . Deviations from the homeostatic ideal may generate a homeostatic emotion , such as pain , thirst or fatigue , that motivates behavior that will restore the body to stasis ( such as withdrawal , drinking or resting ) . </P>
