Hormone: A chemical messenger produced by endocrine glands that regulates body functions.
Explanation
Hormones are secreted by endocrine glands and travel through the bloodstream to target cells. They regulate growth, metabolism, reproduction, mood, and other vital functions. Key hormones include insulin (blood sugar), thyroid hormone (metabolism), and cortisol (stress response). Hormonal imbalances can cause health problems. In adolescents, hormonal changes drive physical and emotional development.
Example
Insulin hormone is produced by the pancreas and regulates blood glucose levels by facilitating glucose uptake into cells.
