Glands make and release hormones.

Hormones are chemicals that stimulate other cells or tissues into action. Because hormones are in your blood, they travel throughout your body. They can affect many organs at the same time.

You have two adrenal glands, one above each kidney. The adrenal glands release several different hormones that help control your blood pressure, heart rate, balance of water and salt, response to stress, and some male-type sex features.
