One may also ask, what 2 hormones are produced by the adrenal glands? The adrenal gland secretes a large amount of the androgen precursor, dehydroepiandrosterone sulfate (DHEAS), which plays a major role in fetoplacental estrogen synthesis and as a subst⁸rate for peripheral androgen synthesis in women. The adrenal glands also regulate salt and volume homeostasis through the steroid hormone, aldosterone. Different glands of the endocrine system are the pituitary gland, thyroid and parathyroid, thymus, pancreas, liver, adrenal, etc. Endocrine glands are ductless glands which secretes a chemical substance called hormone. Size: 4-6 cm long and 2-3 cm wide. When adrenal glands produce excessive amounts of certain hormones, they are called "overactive."

The adrenal gland consists of an outer cortex of glandular tissue and an inner medulla of nervous tissue. The adrenal gland secretes steroid hormones such as cortisol and aldosterone. Together they make up the Endocrine system and all are influenced by one another. The pituitary secretes adrenocorticotropic hormone (ACTH) in response to stressful situations to trigger the well-known fight-or-flight response through cortisol secretion. To be sure you're suffering from cortisol insufficiency it's necessary to have your cortisol levels checked. Adrenal Gland The adrenal gland contains two distinct sections: the cortex and medulla.
