Read the following anatomical locations carefully: (i) Dry surface of the skin (ii) Moist surface of buccal cavity (iii) Inner lining of ducts of salivary glands (iv) Inner lining of pancreatic ducts (v) Proximal convoluted tubule (PCT) (vi) Inner surface of bronchioles How many of the above locations are lined by compound epithelium?

Step-by-step solution

Compound epithelium is made of more than one layer of cells and has a limited role in secretion and absorption. Its main function is to provide protection against chemical and mechanical stresses. According to NCERT, compound epithelium covers the dry surface of the skin, the moist surface of buccal cavity, pharynx, inner lining of ducts of salivary glands and of pancreatic ducts. Thus, locations (i), (ii), (iii), and (iv) are lined by compound epithelium. The proximal convoluted tubule (PCT) of the nephron in the
