Primary: organs develop and remain outside parietal peritoneum. (esophagus, rectum, kidneys) last three of SAD PUCKER Secondary: initially intraperitoneal suspended by mesentary and through course of embryogenesis they went outside peritoneum, mesentary fuse with posterior abdominal wall. Peritoneum only covers the anterior surface of these organs. (ascending and descending colon)

What is the innervation of the parietal peritoneum?

receives somatic nerve supply like the region of abdominal wall that it lines, so pain is well localized.
