Question

Organ in the body which accumulates iodine is

• A. Pituitary gland
• B. Thymus
• C. Thyroid gland
• D. Spleen

Answer 1

The correct option is C Thyroid gland

Organ in the body which accumulates iodine is thyroid gland. Iodine is necessary for the synthesis of the thyroxine hormone. Thyroxine hormone is synthesized in the thyroid gland. It controls the metabolism of proteins, fats and carbohydrates and hence regulates the growth of the body tissues. Iodine is essential for the normal rate of hormone synthesis in the thyroid. Deficiency of iodine in diet results in low secretion of thyroid hormone (hypothyroidism) and enlargement of thyroid gland (simple goitre).

So, the correct answer is 'Thyroid gland'.
