Thyroid function. Figure 2: Pituitary-thyroid feedback. The thyroid gland uses iodine from the diet to make thyroid hormone (thyroxine). Thyroid hormone is stored in the thyroid gland and released into the blood stream as needed by the body.The release of thyroid hormone is controlled by the pituitary gland which makes a hormone called thyroid stimulating hormone (i.e.TSHTSH-Thyroid stimulating hormone; also known as thyrotropin.hyroid function.
