Hormones regulate various biological activities including growth, development, reproduction,

energy use and storage, and water and electrolyte balance.

They are molecules that act as chemical messengers in the body’s endocrine system. Hormones are produced by certain organs and glands and are secreted into the blood or other bodily fluids. Most hormones are carried by the circulatory system to different areas, where they influence specific cells and organs.
