what does the adrenal system do
1 The adrenal cortexâthe outer part of the glandâproduces hormones that are vital to life, such as cortisol (which helps regulate metabolism and helps your body respond to stress) and aldosterone (which helps control blood pressure).he adrenal glands have a multi-functional role in the endocrine system. The two very different parts of these glands, the medulla and cortex, regulate and maintain many of your internal processesâfrom metabolism to the fight-or-flight response.
