Where is t3 and t4 produced?

T3 (triiodothyronine) and T4 (thyroxine) are produced in the thyroid gland, which is located in the front of the neck. The thyroid cells, specifically the follicular cells, synthesize these hormones from iodine and the amino acid tyrosine. T3 and T4 play crucial roles in regulating metabolism, growth, and development in the body.
