    GlossaryHormone Signaling

    chemical messengers travel through blood to regulate body functions

    Hormone signaling, also known as endocrine signaling, is a process where hormones, which are chemical messengers produced by glands, travel through the bloodstream to target organs or cells. These hormones bind to specific receptors on or inside the target cells, triggering a response that regulates various physiological activities such as growth, metabolism, and reproduction.
