Homeostasis is the maintenance of a constant internal environment within an organism.
Homeostasis is maintained by the sensors that send information to the integrating center which detect deviations from the set point. Then a signal is sent to the effectors which counters the change the internal environment.
After eating, a person’s blood glucose rises above normal levels. The pancreas then secretes the hormone insulin that increases the cellular uptake of glucose. This results in a decrease of the blood glucose levels to normal range.
