What is the adrenal gland?
Quick Answer
The adrenal glands are small glands above the kidneys that produce hormones involved in stress response, salt balance, and metabolism. They include a cortex and a medulla with different jobs.
The Full Story
Each person has two adrenal glands, one atop each kidney. The adrenal cortex produces hormones such as cortisol, aldosterone, and small amounts of sex steroids, while the adrenal medulla produces adrenaline and noradrenaline. These hormones help the body respond to stress, regulate blood pressure, and manage salt and water balance. Disorders of the adrenal glands can cause major changes in energy, blood pressure, and body chemistry. Their location and function make them essential endocrine organs.
