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 completes these tasks through its network of glands, which are small but highly important organs that produce, store, and secrete hormones. These glands produce different types of hormones that evoke a specific response in other cells, tissues, and/or organs located throughout the body. The hormones reach these faraway targets using the blood stream. Like the nervous system, the endocrine system is one of your bodyâs main communicators.
