Question

Name the hormone secreted by thyroid,write its function.Why is iodised salt adviceable to us?

Answer 1

• Thyroid-stimulating hormone (TSH) stimulates the synthesis and secretion of thyroid hormones from the thyroid gland. The thyroid gland secretes two hormones:
• Thyroxine ( tetraiodothyronine or T${}_4$ ) and triiodothyronine or T${}_3$. Thyroid hormones stimulate the metabolic activities and increase the oxygen consumption in most of the tissues of the body (exception- brain, lungs, testes, and retina) Iodine is essential for the synthesis of thyroid hormones, therefore, iodized salt is advisable to us.
