The primary function of your thyroid gland is to secrete thyroid hormones, which are responsible for controlling your bodyâs metabolism. The 2 main thyroid hormones are T3 (triiodothyronine) and T4 (thyroxine).The amount of thyroid hormones secreted is controlled by another hormone, called thyroid stimulating hormone (TSH), which is released from the pituitary gland in your head.nother hormone thatâs produced in your thyroid gland is called calcitonin. This hormone, secreted by a small population of cells known as C cells, is involved in regulating the level of calcium in your blood. Last Reviewed: 02 July 2009.
