Understanding the human body

The endocrine system, made up of a diverse group of small, inconspicuous glands, regulates many body functions and is essential in maintaining a constant internal environment. Through chemical messagers called hormones, the endocrine system controls hundreds of vital functions such as body temperature, the use of digested food and reproduction. This volume describes how the endocrine system works and the medical diagnosis and treatment of diseases and disorders of the endocrine system.
