Question

The given figure shows four different types of epithelium P, Q, R and S. Select the correct option regarding this.

• A. P is found in organs involved in secretion such as stomach.
• B. R is found in respiratory tract and helps in gaseous exchange.
• C. Q is found in outer skin layer of sole and palms and is protective in function.
• D. S is ciliated columnar epithelium and is found in inner surface of eyelids.

Answer 1

Answer: (A)

P is found in organs involved in secretion such as stomach.

Figure P depicts non-ciliated simple columnar epithelium along with goblet cells. Its main function is absorption and secretion. Goblet cells secrete mucous which lubricates the lining of respiratory, digestive and reproductive tracts. It prevents the destruction of the stomach lining because of the acidic secretions of its cells.

So, the correct answer is 'P is found in organs involved in secretion such as the stomach'.
