Thyroid gland (weighs about 30 g in adults) is located on either side of the trachea below the larynx. It produces two principal hormones thyroxin (T4; 3,5,3',5'-tetraiodothyronine) and 3,5,3'-triiodothyronine (T3)-which regulate the metabolic rate of the body. Thyroid gland also secretes calcitonin, a Hormone Concerned with calcium homeostasis.
