The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body's growth, metabolism (the physical and chemical processes of the body), and sexual development and function. The hormones are released into the bloodstream and may affect one or several organs throughout the body. Hormones are chemical messengers created by the body.
Metabolism. Hormones that are secreted by the endocrine glands also function to regulate the way the body uses and stores energy. Probably the most well known hormone of this type is insulin which is secreted by the pancreas to control the metabolism of both sugars and lipids.
