The endocrine system consists of glands that make hormones. Your body uses hormones to control growth, development, metabolism, reproduction, mood, and other functions.

The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.

Since your adrenal glands are related to other organs in your endocrine system, your doctor will likely check for signs of disease in your pancreas, sex organs, thyroid gland, and pituitary gland too.

The body's hormones, and the glands that produce them, make up the endocrine system. There are eight major glands, and their job is to regulate the body's metabolism, reproduction, growth and sleep.
