What is the thyroid gland?
The endocrine system is responsible all hormone production, and therefore all of functions that hormones regulate in the body. The endocrine system includes the hypothalamus, pituitary gland, pineal gland, adrenal gland, pancreas, ovaries/testes, parathyroid gland and thyroid gland. The thyroid gland is at the base of the neck and is split into two lobes, one located on either side of the windpipe. It is responsible for producing three hormones that are important for regulating many metabolic processes in the body.
The main hormones produced by the thyroid gland are calcitonin, T3 (tri-iodothyrionine) and T4 (thyroxine). Calcitonin is involved in controlling the tightly regulated calcium levels in the blood.
