WebThe meaning of NEGATIVE FEEDBACK is feedback that tends to dampen a process by applying the output against the initial conditions. WebThe glucagon system works similarly to the insulin negative feedback loop, except to raise blood glucose levels. When there is a decrease in blood glucose concentration, the alpha cells of the pancreas, which are the sensors and controllers, will secrete glucagon into the blood, effectively raising the blood glucose concentration. Glucagon does this by …

"WebSep 12, 2024 · A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics. Cookie.
