تعريف endocrine system في الإنجليزية الإنجليزية القاموس.
A control system of ductless glands that secrete hormones which circulate via the bloodstream to affect cells within specific organs
the system of glands that produce endocrine secretions that help to control bodily metabolic activity
The bodily system that consists of the endocrine glands and functions to regulate body activities. Group of ductless glands that secrete hormones necessary for normal growth and development, reproduction, and homeostasis. The major endocrine glands are the hypothalamus, pituitary, thyroid, islets of Langerhans, adrenals, parathyroids, ovaries, and testes. Secretion is regulated either by regulators in a gland that detect high or low levels of a chemical and inhibit or stimulate secretion or by a complex mechanism involving the hypothalamus and the pituitary. Tumours that produce hormones can throw off this balance. Diseases of the endocrine system result from over-or underproduction of a hormone or an abnormal response to a hormone
