The kidneys reside in the abdominal cavity, specifically in which space?

The kidneys are located in the retroperitoneal space, meaning they lie behind the peritoneal lining of the abdominal cavity. The peritoneal cavity contains the intraperitoneal organs that are wrapped in peritoneum, while the kidneys sit outside this space, against the posterior abdominal wall and surrounded by fat and the renal fascia. Their retroperitoneal position explains why they’re not within the peritoneal cavity and helps distinguish them from other abdominal organs that develop inside the peritoneum. They are not in the thoracic or cranial cavities, which are separated by the diaphragm and skull, respectively.
