The endocrine system, or hormone system of the body consists of the pineal, pituitary, thyroid, parathyroids, adrenals, testes and ovaries. The endocrine system regulates many of the body functions.

The glands and parts of glands which produce endocrine secretions, i.e., hormones, which help to integrate and control bodily metabolic activity and physiological functions; e.g.,. the pituitary, thyroid, parathyroids, adrenals, pancreatic islets of Langerhans, ovaries, and testes.

A major body regulating system in humans and other vertebrates responsible for growth, sexual development, and reproduction. The endocrine system consists of a variety of organs called endocrine glands that secrete hormones into the bloodstream. The human endocrine glands include the testicles, ovaries, pancreas, adrenal glands, thyroid, parathyroid and thymus, as well as others.

a system of specialized cells, tissues, and ductless glands that excretes hormones and shares with the nervous system responsibility for maintaining constant internal body conditions and responding to changes in the envoronment

is a term for a group of glands, specifically the pituitary, thyroid, thymus, pancreas, adrenal, testes and ovaries.

The system of ductless glands whose secretions are released directly into the bloodstream and affect organs elsewhere in the body (e.g., adrenal gland).

(Système endocrinien) Group of organs and tissues releasing hormones into the blood to regulate the growth, development and functioning of many tissues and coordinate an organism’s metabolic processes.(Microsoft®. Encarta Encyclopedia® 99. ©1993-1998 Microsoft Corporation.)

A system of glands that release and secrete hormones into the bloodstream where they travel to “target organs” or tissues to exert their effect. The major glands of the endocrine system are the pituitary, thyroid, parathyroid, and adrenal, glands and the pancreas, testes, and ovaries.

The endocrine system refers to all of the body's hormone-secreting glands. This system works in conjunction with the nervous system to control the production of hormones and their release into the circulatory system.

This is the hormonal system that produces internal secretions which act upon organs.

The body system that consists of glands and regulates your hormones.

System of glands including the hypothalamus, pituitary, thyroid, adrenals and testicles or ovaries.

bodily system of glands which produce and secrete hormones into the bloodstream Humans as organisms

A system of ductless glands that discharge their secretions (hormones) into the extracellular fluid around capillaries and hence into the bloodstream. The hormones secreted by the endocrine glands are important integrators of bodily functions. See also hormone.

One of the major regulatory systems of the body. It regulates the "slower" processes such as growth and reproduction, while the nervous system regulates the "faster" processes such as heartbeats and muscle movements. The endocrine system works by secreting special "messenger chemicals" called hormones.

The complex mechanism of interaction between hormones and glands.

An inter-related series of glands that secrete hormones to regulate and control all of the bodyâ€(tm)s major functions.

Endocrine system is body control system composed of a group of glands that maintain a stable internal environment by producing chemical regulatory substances called hormones.

A group of glands which maintain the body's internal environment through the production of hormones. Imbalances in this system can sometimes lead to increased or decreased hair. Glands in the endocrine system include the pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries, and testes

The endocrine system is a control system of ductless glands that secrete chemical messengers called hormones that circulate within the body via the bloodstream to affect distant cells within specific organs. Endocrine glands secrete their products immediately into the blood or interstitial fluid, without storage of the chemical. Hormones act as "messengers," and are carried by the bloodstream to different cells in the body, which interpret these messages and act on them.
