The thyroid gland is an important gland in the endocrine system. Located in the neck, the thyroid gland consists of two lobes which sit to the right and the left of the trachea, or windpipe. The two lobes are connected by a thyroid tissue that runs across the front of the trachea. The thyroid produces a hormone called thyroxine, which, once released into the bloodstream, controls the body’s metabolism, determines the rate at which the heart moves, and the movement of the gastrointestinal tract. Thyroxine affects bone loss as well as how the body makes and uses sugar. The pituitary gland plays an important role, releasing its own hormone called thyroid stimulating hormone, or TSH, which stimulates the thyroid to make and release more thyroxine into the body.
