Substances formed in one part of the body and diffused or carried by the blood to other parts of the body, the functions of which they regulate and coordinate.
Hormones are produced by specialized cells and organs, such as the pituitary gland, thyroid gland, adrenal glands, and gonads. They enter the bloodstream and are delivered to target organs, where they interact with specific receptors, triggering a cascade of biochemical reactions.
Hormones regulate many processes in the body - growth, development, metabolism, reproduction, behavior, etc. Disruption of the endocrine glands and imbalance of hormones can lead to serious diseases. Therefore, the hormonal system requires careful monitoring and regulation.
