The thyroid is a small, butterfly-shaped gland located at the base of your neck. It is one of many glands in the endocrine system in the body that regulate the function, growth and development of virtually every cell, tissue and organ in the body. Endocrine glands secrete hormones directly into the bloodstream.
The thyroid hormone thyroxine is also called T4 and is scientifically known as 3, 5, 3â5,â-tetraiodothyronine. It is a hormone produced by the thyroid gland and is a very important hormone in the body. The function of thyroxine involves the stimulation of oxygen consumption which leads to tissue and cellular metabolism.Along with that, it is used as a biochemical indicator of the functioning of the thyroid gland.hyroxine is also converted by the kidney and the liver and turned to other kinds of hormones. Because it plays such an important role in numerous functions of the body, having too much or too little of the thyroid hormone can cause problems in the body.
