Question

Explanation:

Retroperitoneal organs lie behind the peritoneum. The stomach and most of the large intestine are intraperitoneal (within the peritoneum). The urinary bladder is subperitoneal (below the peritoneum when full, but has a different positioning). Kidneys are retroperitoneal, as they are located posterior to the peritoneum, between the posterior abdominal wall and the peritoneum.
