Detailed explanation-1: -Stratified Epithelium This epithelium protects against physical and chemical wear and tear. The stratified epithelium is named by the shape of the most apical layer of cells, closest to the free space. Stratified squamous epithelium is the most common type of stratified epithelium in the human body.

Detailed explanation-2: -Functions of Simple Cuboidal Epithelium These cells generate cerebrospinal fluid. In the thyroid, these cells line the thyroid follicles and are called follicular cells. This tissue actively takes up iodine and creates thyroid hormone precursors, which are then processed and secreted into the blood.

Detailed explanation-3: -Cholangiocytes are the simple cuboidal epithelial cells of the bile duct. Furthermore, they contribute to bile secretion.

Detailed explanation-4: -By lining the surface of various ducts of various glands and organs, simple cuboidal cells are able to provide a layer of protection from abrasion, foreign particles, invading bacteria and excessive water loss (due to its selective permeability) to the underlying tissue.
