The endocrine system is the system of glands that produce hormones which go directly into the bloodstream, such as the pituitary or thyroid glands. relating to the system in your body that produces hormones (endo- (from endon) + krinein )
Producing secretions (especially hormones) that are distributed in the body by way of the bloodstream
1 Secreting directly into the bloodstream, as a ductless gland 2 Of or pertaining to the endocrine glands or their secretions
adj Secreting internally Endocrinology is the physiology of internally secreting glands
Secretions from an endocrine gland such as hormones, which diffuse into the bloodstream to be carried around the body They produce a physiological effect at distant sites Adrenaline is secreted from an endocrine gland
Relating to internal secretion: relating to glands that secrete hormones internally directly into the lymph or bloodstream
The endocrine system is the group of organs that produce hormones and excrete them into the blood stream through which they travel to the tissues that use them
n. Any of various glands producing hormonal secretions that pass directly into the bloodstream. The endocrine glands include the thyroid, parathyroids, anterior and posterior pituitary, pancreas, adrenals, pineal, and gonads. Also called ductless gland
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
