Learn about the endocrine system, its functions, organs, hormones, and conditions that can affect it. The endocrine system uses hormones to regulate metabolism, growth, reproduction, and more.

The endocrine system [1] is a messenger system in an organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant organs.

Learn about the glands and organs that make up the endocrine system and how they use hormones to regulate your body's functions. Find out the roles of the hypothalamus, pituitary, thyroid, adrenal, pancreas, and reproductive glands.

Learn about the endocrine system, a collection of ductless glands that produce and secrete hormones into the bloodstream. Find out the functions, parts, and diseases of the endocrine system and how it regulates metabolism, growth, and development.

Endocrine system, any of the systems found in animals for the production of hormones, substances that regulate the functioning of the organism. Such a system may range, at its simplest, from the neurosecretory, involving one or more centres in the nervous system, to the complex array of glands

human endocrine system, group of ductless glands that regulate body processes by secreting chemical substances called hormones. Hormones act on nearby tissues or are carried in the bloodstream to act on specific target organs and distant tissues.

Finally, the article presents various endocrine systems in which hormones produced in several organs cooperate to achieve the desired regulatory effects. The discussions focus primarily on the system responses in normal, healthy people.

Throughout life the endocrine system and the hormones it secretes enhance the ability of the body to respond to stressful internal and external stimuli. The endocrine system allows not only the individual organism but also the species to survive.
