The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.
-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, whose role is to transfer information from one set of cells to another to coordinate the functions of different parts of the body.
Regardless of being unicellular or multicellular, any individual form of life capable of growing, metabolizing nutrients, and usually reproducing is an organism.
