Which cavity houses the kidneys?

Understanding where organs sit in the body’s cavities helps explain this. The kidneys reside in the abdominal cavity, specifically in the posterior abdominal wall and behind the peritoneum (retroperitoneal). They span roughly from the 12th thoracic vertebra to the 3rd lumbar vertebra and are protected by fat and fascia. The pelvic cavity mainly contains the bladder and reproductive organs, the thoracic cavity holds the heart and lungs, and the cranial cavity houses the brain. Because the kidneys are located in the abdominal cavity, behind the peritoneal lining, the abdominal cavity is the correct location.
