Endocrine Signaling

Meaning

Endocrine Signaling is a fundamental mode of intercellular communication where specialized glands secrete chemical messengers, known as hormones, directly into the bloodstream. These hormones travel systemically to target cells and tissues distant from the site of secretion, initiating a specific physiological response. This process is the core mechanism by which the body regulates growth, metabolism, reproduction, and homeostasis.
