Which description correctly reflects peritoneal structure?

• A. The peritoneum is solely the visceral layer.
• B. The peritoneum is not associated with the abdominal cavity.
• C. The peritoneum has only arterial supply.
• D. The peritoneum consists of parietal and visceral layers.

Answer: (D)

The peritoneum is a serous membrane that lines the abdominal cavity and covers the abdominal organs. It has two layers: the parietal peritoneum, which lines the cavity wall, and the visceral peritoneum, which covers the organs. These layers are continuous with each other and are separated by a small amount of lubricating fluid in the peritoneal cavity, allowing smooth movement of the viscera. This arrangement—parietal lining the cavity and visceral covering the organs—best describes the peritoneum. Statements claiming it is solely the visceral layer, not associated with the abdomen, or that it has only arterial supply are incomplete or inaccurate because they ignore the distinct parietal layer, the cavity with fluid, and the vascular nature that includes both arteries and veins.
