The Simple cuboidal epithelium forms thyroid gland and secretes hormones is shown in the picture attached.
Its main functions are secretion and absorption. It has an abundance of organelles to facilitate active transport frequently found in glands, such as salivary glands, the thyroid gland, and the pancreas, where its function is secretion.
The epithelial cells tend to be cubical in form after they are inactive, however additional columnar after they are actively secreting hormones.
The epithelial cells accumulate iodine from the blood and use this component within the synthesis of thyroglobulin, an oversized compound protein that forms the mixture.
