The thyroid gland, a butterfly-shaped gland in the neck area regulates cellular metabolism. Its hormones--triiodothyronine or T3 and thyroxine or T4, acts on target tissues. They act on practically every cell in the body to increase metabolic rate and long bone growth, protein synthesis and metabolism of nutrients to obtain energy. This hormone leads to heat generation in humans therefore, its role affects body temperature. Iodine must be available in the bloodstream to produce thyroid hormones. Thyroid hormones affect the heart's output and heart rate, brain development in the young, the uterine lining in females during the menstrual cycle, breathing rate and metabolism.
