Follicular Cells & the Synthesis of Thyroid Hormones

The video explains the synthesis and function of thyroid hormones, focusing on the role of follicular cells in the thyroid gland. It details the process of iodination, formation of T3 and T4 hormones, and their release into the bloodstream. The video also covers the conversion of T4 to the more active T3 form, and the inactivation and elimination of thyroid hormones through deiodination and glucuronidation.
