KNOW YOUR BODY; Adrenal glands.

Where are they? The body has two grape-sized adrenal glands, one sitting above each kidney. They have an inner core, the medulla, and an outer skin, the cortex. What do they do? Hormones produced here are vital in controlling chemistry. If adrenal hormone levels are too high or low, the effects can be serious. The medulla produces adrenaline and noradrenaline, which help to control heart rate and blood pressure. The cortex produces steroid hormones aldosterone, which balances sodium and potassium, hydrocortisone, the energy hormone, and the sex hormones testosterone, oestrogen and progesterone. What can go wrong? Disorders may involve the overproduction or underproduction of hormones, leading to Cushing's syndrome and Addison's disease respectively, which need urgent treatment.
