The endocrine system functions through a network of ductless glands that secrete hormones into the bloodstream to regulate physiological processes in distant target cells via specific receptor interactions. The core regulatory mechanism is negative feedback, a homeostatic loop where the output of a response inhibits further signal generation to maintain internal conditions near a set point. This mechanism operates within the domain of human physiology, specifically distinguishing slow-acting, long-duration chemical signaling from the rapid, wired transmission of the nervous system to ensure metabolic stability and energy balance.
