The endocrine system comprises a number of glands that produce hormones with a varied array of vital functions. Hormones are chemical substances that are secreted by organs or by cells of organs in one part of the body and are carried by the bloodstream to other organs or tissues, where they control or regulate the development or function of those structures.
