The correct answer is: a feedback mechanism.
The bionic pancreas is bio-engineered device used for the regulation of blood sugar levels in order to maintain body homeostasis. The bionic pancreas includes a sensor that monitors blood sugar levels and sends a signal to a separate device that will then release the appropriate hormone into the bloodstream to return blood sugar levels back to normal. This device is very functional because of its ability to dose insulin and glucagon based on continuous sugar blood measurements.
