Thyroid gland
The thyroid is a butterfly-shaped gland that lies in front of the windpipe (trachea), just below the voice box (larynx). The thyroid gland uses iodine from food to make two thyroid hormones: thyroxine (T4) and triiodothyronine (T3). The thyroid gland stores these hormones and releases them as they are needed.
