The thyroid plays an important role in regulating the body's metabolism and calcium balance.
The thyroid gland produces and secretes T4 and T3, which are hormones involved in many aspects of growth, development, and metabolism. 

The thyroid gland also secretes calcitonin. The function of calcitonin is to inhibit the amount of resorption of calcium from the bone and to regulate the amount of calcium in the blood stream. The thyroid's C-cells (parafollicular cells) are stimulated to secrete calcitonin when there is a high concentration of calcium in the blood stream.
