Feedback+Mechanisms+in+the+Endocrine+System

The two types of feedback mechanisms are negative feedback  and positive feedback
 * Negative feedback decreases the deviation from an ideal normal value, and is important in maintaining homeostasis. Most endocrine glands are under the control of negative feedback mechanisms.


 * Negative feedback mechanisms act like a thermostat in the home. As the temperature rises (deviation from the ideal normal value), the thermostat detects the change and triggers the air-conditioning to turn on and cool the house. Once the temperature reaches its thermostat setting (ideal normal value), the air conditioning turns off. An example of negative feedback is the regulation of the blood calcium level.


 *  Positive feedback  is when a system tends to increase output. The product of a reaction influences or increases the forward direction of the system: in  positive feedback systems  the presence of a product (or signal) results in an increase in the production (amplification) of that product (or signal).
