What controls the change that has to happen to make things normal again?

• response - increased glucose uptake into cells

• receptor/sensor - pancreas/brain detect high blood glucose

• stimulus - high blood glucose level following a meal

• control center - pancreas cells secrete insulin

• response - increased glucose uptake into cells

• receptor/sensor - brain/pancreas detect high blood glucose

• stimulus - high blood glucose level following a meal

• control center - pancreas cells secrete insulin
