Hormones are chemicals secreted by endocrine glands: the pituitary gland, adrenal glands, pancreas or even the thyroid gland that regulate the rate of our metabolism and affect our body cells depending on the purpose.

Today we look at the meaning of the thyroid gland in our body.

About thyroid gland

The thyroid gland is located below the larynx, on the front surface of the trachea. By the action of the pituitary gland – thyrotropin (TSH) it secretes 2 hormones into the bloodstream

  1. T3 – thyroxine
  2. T4 – triiodothyronine

For the production of these hormones, the body needs material such as iodine, which is supplied with food. Iodine deficiency in the daily diet causes disorders in the secretion of thyroid hormones. As a result, the increased amount of the TSH hormone causes the thyroid gland to grow, which we call goiter.
