Name the hormone secreted by the thyroid gland. What is it's function? Why is the use of iodised salt advisable?
Answers
the hormone which is secreted by thyroid is thyroxine...It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.Iodine is needed by the thyroid gland for the production thyroxin hormone. This hormone regulates fat, protein and carbohydrate metabolism in our body. If this is in deficient quantity then the neck will swell up due to the enlargement of thyroid gland. This deficiency disease is known as goitre.
Therefore the iodised salt is advised.
