*collection of ‘glands’ that secrete ‘hormones’ into the ‘circulatory system’ to be carried to a ‘target organ’*

(the major endocrine glands include the…)
‘pineal gland’
‘pituitary gland’
‘pancreas’
‘ovaries’
‘testes’
‘thyroid gland’
‘parathyroid gland’
‘hypothalamus’
‘gastro-intestinal tract’
‘adrenal glands’

(the endocrine system is in contrast to the exocrine system, which secretes its hormones to the outside of the body using ‘ducts’)
(the endocrine system is an information signal system like the nervous system, yet its effects and mechanism are classifiably different)
(the endocrine system’s effects are slow to initiate, and prolonged in their response, lasting from a few hours up to weeks)
(the ‘nervous system’ sends information very quickly, and responses are generally short-lived)
(in ‘vertebrates’, the ‘hypothalamus’ is the ‘neural control center’ for all ‘endocrine systems’)
(the ‘field of study’ dealing with the ‘endocrine system’ + its disorders is ‘endocrinology’, a branch of ‘internal medicine’)
Special features of endocrine glands are, in general, their ductless nature, their vascularity, and commonly the presence of intracellular vacuoles or granules that store their hormones.
In contrast, exocrine glands, such as salivary glands, sweat glands, and glands within the gastrointestinal tract, tend to be much less vascular and have ducts or a hollow lumen.
In addition to the specialized endocrine organs mentioned above, many other organs that are part of other body systems, such as bone, kidney, liver, heart and gonads, have secondary endocrine functions.
For example, the kidney secretes endocrine hormones such as erythropoietin and renin.
Hormones can consist of either amino acid complexes, steroids, eicosanoids, leukotrienes, or prostaglandins.
(a number of glands that signal each other in sequence are usually referred to as an axis, for example, the ‘hypothalamic-pituitary-adrenal axis’)
(as opposed to endocrine factors that travel considerably longer distances via the ‘circulatory system’, other signaling molecules, such as ‘paracrine factors’ involved in ‘paracrine signalling’ diffuse over a relatively short distance)

(the word “endocrine” derives from…)
the greek words ἐνδο- (endo-) …>
(‘inside, ‘within’)
and κρίνειν krinein –>
(to ‘separate’ / ‘distinguish’)
