State
A negative feedback loop reverses the direction of a stimulus, pushing a rising level down or a falling level up, and dominates homeostatic correction.
Show
Rising blood glucose triggers insulin release, which lowers glucose back toward its set point.
Watch for
"Negative" names the loop's corrective direction, not a bad outcome — a loop raising a too-low level is negative feedback too.
