Organs that lie outside the abdominal cavity such as the duodenum, pancreas, urinary bladder and rectum are

  • A. covered with parietal peritoneum.
  • B. covered with visceral peritoneum.
  • C. retroperitoneal.
  • D. covered with serous membranes
Correct Answer: C

Rationale: The correct answer is C: retroperitoneal. Organs like the duodenum, pancreas, urinary bladder, and rectum are considered retroperitoneal because they lie behind the parietal peritoneum, which lines the abdominal cavity. They are not completely covered by visceral peritoneum (B) as they are not suspended in the abdominal cavity. They are not covered by parietal peritoneum (A) as this layer lines the abdominal wall. While these organs are covered with serous membranes (D), the defining characteristic is their location behind the peritoneum, making option C the most accurate choice.
