What is the term for the space behind the peritoneum?

The space behind the peritoneum is the retroperitoneal space. The peritoneum lines the abdominal cavity, and organs that lie within this lining and inside the cavity are intraperitoneal. Those that sit between the peritoneum and the posterior abdominal wall—behind the lining—are retroperitoneal. This term literally means “behind the peritoneum.” It’s used to describe structures like the kidneys and parts of the duodenum and pancreas, as well as major vessels, that are located I with the posterior abdominal wall rather than fully enclosed by peritoneum. The other terms describe either structures inside the peritoneal cavity (intraperitoneal/intra-abdominal) or aren’t standard for this concept.
