When youâre comparing it to something else, itâs better. When you say that it is better than anything else, itâs the best. If you understand this, you already know what a comparative and a superlative are. Words that compare one thing to another (e.g., better, older) are called comparatives.
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).
The purpose of your thyroid gland is to make, store, and release thyroid hormones into your blood. These hormones, which are also referred to as T3 (liothyronine) and T4 (levothyroxine), affect almost every cell in your body, and help control your bodyâs functions.he amount of thyroid hormone made by your thyroid gland is adjusted by a gland in the brain called the pituitary. Another part of your brain, the hypothalamus, helps the pituitary. The hypothalamus sends information to the pituitary gland, the pituitary in turn controls the thyroid gland.
