  • The thyroid gland, small as it is, is one of the most important glands in the body.
  • This gland is responsible for the proper functions of the vital organs.

The thyroid gland is located beneath the Adam’s apple just in the base of your neck. It is small and shaped like a butterfly. Though it is small in size, this gland plays a vital role in the body. The thyroid gland accounts for the many functions of different organs of the body and this includes the liver, heart, kidneys, skin and brain. To ensure that the whole body is healthy, one has to make sure that the thyroid gland functions properly.

The thyroid gland is also responsible for the hormone that tells the cells to do their function precisely. The thyroid gland produces thyroid hormone through the intake of Iodine which serves as the fuel to the body. You can get Iodine from milk, bread and iodized salt.

The thyroid extracts from the bloodstream then uses it to make the hormones, Thyroxine or T4 which contains 4 inside atoms and triiodothyronine or T3 which contains 3 iodine atoms. The pituitary gland gives the thyroid directions. The TSH, thyroid stimulating hormone, acts like a message sent to the thyroid gland so that it will know how much thyroid hormone it has to produce.


The levels of TSH in the bloodstream may rise or fall depending on the production of the thyroid hormone for the body’s needs. If there is a high level of TSH, it commands the thyroid to create more thyroid hormone. Low levels of TSH signals that the thyroid should be producing lesser hormones.
