Thyroid is a butterfly-shaped gland, that is located in the neck, below Adam's Apple.

The main function of thyroid gland is to convert iodine - which is found in foods - in thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Only thyroid gland has cells that are capable of absorbing iodine.

Thyroid takes iodine from food, supplements and iodized salt and combines it with amino acids to produce thyroid hormones, T3 and T4. These hormones regulate the metabolism of the human body, also they regulate the functions of internal organs. Thyroid hormones influence every internal organ, every tissue and every cell in the body.

T3 and T4 through pass through the body, via the bloodstream, and help cells to convert oxygen and calories into energy.

Thyroid or thyroid is a hormone producing glands. It is located in the front part of the neck. It produces several hormones including thyroxine and calcitonin.

Thyroxine controls the body's cell mechanism. Higher the amount of thyroxine released by the thyroid in the bloodstream, greater is the rate at which cells convert oxygen and nutrients into energy and heat for the body's use. During the period of growth of a child thyroid hormones trigger an increase in growth rate.  Thyroid hormones also stimulates mental activity and increases the activity of the other hormone-producing glands.

Calcitonin hormone produced by thyroid the kidneys to discharge more calcium in the urine and raises the amount of calcium stored in the bones. In this way it regulates the level of calcium in the blood.
