By Matt Fowler. ABC has picked up Marvel's Agent Carter for a second season, while Agents of SHIELD will be back for Season 3. While Agents of SHIELD's pick up was more or less expected, the Agent Carter news comes as an awesome semi-surprise since its fate was more up in the air.
Where are the adrenal glands? The adrenal glands are small glands that sit on top of the kidneys in the retroperitoneum (i.e. the deepest part of the abdomen). They are several centimeters in length and each weighs 4-6 grams.
Adrenal Stress Index. The adrenal glands are two tiny organs that reside just above the kidneys. Each one weighs about as much as a walnut, but they have a key role in regulating the body's metabolism. Each adrenal gland has two functional zones that have unique jobs in the body. The outer cortex secretes adrenal steroids (Cortisol, DHEA, and Aldosterone). The inner medulla secretes adrenaline and noradrenaline. Cortisol, DHEA, and adrenaline are the three main adrenal stress hormones.
