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).
Video: The Thyroid Gland: Functions, Calcitonin & TSH. Your thyroid gland produces the hormones T3 and thyroxine (T4), which play a role in metabolism. Your thyroid also produces calcitonin, which helps regulate blood calcium levels. In this lesson, you will learn about the thyroid gland and its hormones, including how they are regulated by TSH.
