The proximal and distal of the kidney, the epithelium surrounding the colloid in the thyroid gland, the front face of the lens, the choroid plexus, the free face of the ovary, the most recent parts of the serous glands, the drainage channels of most glands and respiratory bronchioles. This type of epithelium allows the secretion and reabsorption

The stomach surface, small intestine and colon, gallbladder and uterine cavity.

This epithelium is divided into keratinized and non-keratinized. Keratinized epithelium is found in the skin and filiform papilla, non-keratinized epithelium is found in the lip, oral, pharynx, true vocal cords and vaginal epithelium.

Some sweat and salivary glands have this type of epithelium in the duct channels.
