Explanation by: Admin

The lungs are enclosed in a pleural membrane, which consists of two layers:

  • The visceral pleura, which is attached to the surface of the lungs.
  • The parietal pleura, which lines the chest cavity.

The space between these two layers, known as the pleural cavity, contains a small amount of fluid that allows the lungs to expand and contract smoothly during breathing.

Why other options are incorrect:

  • (A) Pericardium – This is the membrane that surrounds the heart, not the lungs.
  • (B) Peritoneum – This is the membrane that lines the abdominal cavity and covers the organs within it.
  • (D) None of these – Incorrect, because the pleural membrane is the correct answer.
