Endocrine glands include: 1  Adrenal glands: Two glands that sit on top of the kidneys that release the hormone cortisol. 2  Hypothalamus: A part of the lower middle brain that tells the pituitary gland when to release hormones.  Ovaries: The female reproductive organs that release eggs and produce sex hormones.
The major endocrine glands include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus, gastrointestinal tract and adrenal glands. The endocrine system is in contrast to the exocrine system, which secretes its hormones using ducts.or example the kidney secretes endocrine hormones such as erythropoietin and renin. A number of glands that signal each other in sequence are usually referred to as an axis, for example, the hypothalamic-pituitary-adrenal axis.
