Article Excerpts about Adrenal glands

Cortisol is normally produced by the adrenal glands, located just above the kidneys. It belongs to a class of hormones called glucocorticoids, which affect almost every organ and tissue in the body. Scientists think that cortisol has possibly hundreds of effects in the body. Cortisol's most important job is to help the body respond to stress. Among its other vital tasks, cortisol:

  • helps maintain blood pressure and cardiovascular function;
  • helps slow the immune system's inflammatory response;
  • helps balance the effects of insulin in breaking down sugar for energy; and
  • helps regulate the metabolism of proteins, carbohydrates, and fats.

Because cortisol is so vital to health, the amount of cortisol produced by the adrenals is precisely balanced. Like many other hormones, cortisol is regulated by the brain's hypothalamus and the pituitary gland, a bean-sized organ at the base of the brain. (Source: excerpt from Addison's Disease: NIDDK)

Summary Information: Adrenal glands

Adrenal glands: The adrenal glands are a pair of endocrine glands, one located on the top of each kidney. The adrenal glands produce a variety of hormones, chemical substances that help to regulate a wide variety of the body's processes. The adrenal glands and the hormones they produce play a big role in such processes as metabolism, water and electrolyte balance, sexual development and function, the immune system, and the stress response.

The adrenal glands include two regions, the adrenal cortex and the adrenal medulla, which each produce different hormones. Adrenal hormones include the catecholamines epinephrine and norepinephrine, and the adrenal steroid hormones: adrenal androgen hormones, mineralocorticoids, and glucocorticoids. Conditions that can afflict the adrenal glands include Addison's disease, Cushing's syndrome, pheochromocytoma, hyperaldosteronism, adrenal tumors, adrenal cancer, and trauma.
