The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3).Thyroid cells are the only cells in the body which can absorb iodine. These cells combine iodine and the amino acid tyrosine to make T3 and T4.he function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3).
What does my thyroid gland do? The thyroid gland produces hormones which regulate the bodyâs metabolic rate as well as heart and digestive function, muscle control, brain development and bone maintenance.he release of thyroid hormones from the thyroid gland is controlled by thyrotrophin-releasing hormone (TRH) from the hypothalamus in the brain and by thyroid stimulating hormone (TSH) produced by the pituitary gland. This forms part of a feedback loop called the hypothalamic-pituitary-thyroid axis.
