Human Thyroid Gland

The butterfly-shaped gland that sets your metabolic pace/The Human Body

The thyroid gland wraps around the front of the trachea just below the larynx. It produces hormones T3 and T4 that regulate metabolism, heart rate, and body temperature. Despite weighing only about 25 grams, it influences nearly every cell in the body.
