hormone action mechanisms

Hormone action mechanisms involve chemicals released by glands into the bloodstream to regulate body functions. When a hormone reaches its target, it binds to specific receptors on or inside cells. This binding triggers a series of internal signals that alter cell activity, such as turning genes on or off, or changing how the cell performs its tasks. These processes help control growth, metabolism, mood, and other vital functions, maintaining the body’s balance and response to various needs or stresses.
