The thyroid gland is a butterfly-shaped organ located in the neck that plays a critical role in regulating the body's metabolism. It produces hormones such as thyroxine (T4) and triiodothyronine (T3), which influence various bodily functions, including metabolic rate, heart function, digestive health, muscle control, brain development, and bone maintenance. These hormones are crucial for the normal functioning of many systems in the body and can impact reproductive health.
