The adrenal gland is a part of most mammals' bodies. It is near the kidneys. Its name tells about its position (ad – "near", and renes – "kidneys"). It helps control the levels of stress. It is involved in the production of steroid hormones. Among these hormones are Cortisol and Adrenaline. The gland is made up of two types of tissues: the centrally located tissue is called the adrenal medulla and outside this lies the adrenal cortex.
