It is made of more than one layer of cells and thus has a limited role in secretion and absorption.
Their main function is to provide protection against chemical and mechanical stresses.
They cover the dry surface of the skin, moist surface of buccal cavity, pharynx, inner lining of ducts of salivary glands and pancreatic ducts.
