प्रश्न
What will happen if intake of iodine in our diet is low?
उत्तर
The thyroid gland secretes the hormone thyroxine which controls the rate of metabolism of carbohydrates, fats, and proteins in the body. Iodine is required for the release of thyroxin from the thyroid gland. If iodine is deficient, thyroxine hormone will be deficient in the body and will cause goitre. The neck appears to be swollen due to enlargement of the thyroid gland.
