Which statement correctly defines the peritoneum?

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

Answer: (D)

The peritoneum is a serous membrane that lines the abdominal cavity and covers its organs. It has two continuous layers: the parietal peritoneum lining the cavity wall and the visceral peritoneum covering the organs. These layers are connected and form reflections that create mesenteries and omenta, providing support and a route for vessels and nerves while allowing smooth movement of the viscera due to the lubricating fluid in the cavity. It is supplied by both arteries and veins, not only arteries, and it is indeed associated with the abdominal cavity, lining it and enveloping the organs. This two-layer arrangement best describes the peritoneum.
