A Correct answer
Explanation

The peritoneum is a serous membrane that lines the abdominal cavity (parietal peritoneum) and covers most abdominal organs (visceral peritoneum). It produces a lubricating fluid that reduces friction between organs during digestion and movement. The peritoneal cavity is a potential space containing this fluid and is crucial for immune responses in the abdomen.
