Thyroid follicles. Computer artwork of cells of thyroid follicles (pink,purple). Thyroid follicles are found in the thyroid gland. They consist of a layer of epithelial cells (purple) around a central storage chamber (large,dark pink). The cells produce the thyroid hormones tri-iodothyronin (T3) and thyroxine (T4) and secrete them into the central chamber where they are stored as the glycoprotein thyroid colloid (red). Thyroid hormones regulate the body's metabolism. They are transported from the thyroid gland around the body in blood vessels (red,branching) | |
