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
that regulate the way the body uses energy.
glands are four tiny glands located behind the thyroid gland. The
parathyroid glands produce a substance (parathyroid hormone) that helps control
the amount of calcium in the blood.
