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 Structure of the Endocrine System. The endocrine system is composed of the following endocrine glands; thyroid, parathyroid, pituitary, pineal and adrenal.The endocrine glands secrete hormones, which are messenger molecules, into the interstitial fluid in the bloodstream.These released hormones affect nearly every cell, organ, and function of the human body.or example, the endocrine system influences things like cell growth, whilst faster processes, like breathing are controlled by the nervous system. The nervous and endocrine systems are different systems, yet are complementary systems and work together to help the body function properly.
