• B. Its main function is protection against chemical and mechanical stress.
• C. They cover inner lining of ducts of salivary glands.
• D. All of these

Answer 1

Answer: (D)

The compound epithelium is made of more than one layer (multi-layered) 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, the moist surface of the buccal cavity, pharynx, the inner lining of ducts of salivary glands, and of pancreatic ducts.
