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 endocrine system is made up of pituitary, pineal, thyroid, parathyroid and adrenal glands, pancreatic islet cells (also known as islets of Langerhans) and the ovaries or testicles. 1  The pituitary, pineal and parathyroid glands are neuroendocrine glands. Neuroendocrine cells in the digestive system regulate intestinal movements and the release of digestive enzymes. 2  Neuroendocrine cells in the respiratory system are believed to play a role in the developmental stages of the respiratory organs. 3  They also regulate respiratory function.
