Answers
Answer:
The thyroid gland uses iodine from food to make two thyroid hormones: triiodothyronine (T3) and thyroxine (T4). It also stores these thyroid hormones and releases them as they are needed. The hypothalamus and the pituitary gland, which are located in the brain, help control the thyroid gland. The hypothalamus releases thyrotropin-releasing hormone (TRH), which stimulates the pituitary gland to release thyroid-stimulating hormone (TSH). When the hypothalamus and pituitary are working normally, they sense when:

When the hypothalamus and pituitary are working normally, they sense when:Thyroid hormone levels are low, so they secrete more TRH and TSH, which stimulates the thyroid to make more hormones.
