Question

Filo · Accepted Answer

The follicular cells of the thyroid gland synthesize two thyroid hormones; Tetraiodothyronine (T

_{4}

) and the C-cells of thyroid gland produces Thyrocalcitonin. The function of these hormones are as follows

Thyroxine is the main hormone (80% in thyroxine form) secreted into the bloodstream by the thyroid gland.
It is the inactive form and most of it is converted to an active form called as triiodothyronine (T $_{3}$ ) by organs such as the liver and kidneys.
Both T $_{4}$ and T $_{3}$ are synthesized from tyrosine and iodine.
The thyroid hormones control the metabolism of carbohydrates, protein and fats. They play an important role in regulating the Basal Metabolic Rate (BMR)
