Difference Between Peritoneal and Retroperitoneal

Key Difference

The key difference between peritoneal and retroperitoneal lies in the location of organs within the abdominal cavity. Peritoneal organs are enclosed by the peritoneum, a membrane that lines the abdominal cavity. Retroperitoneal organs are located behind (retro) the peritoneum and are not completely enclosed by this membrane.

Comparative Analysis

1. Location in Abdomen:
   • Peritoneal: Inside the peritoneal lining.
   • Retroperitoneal: Behind the peritoneal lining.
2. Examples of Organs:
   • Peritoneal: Stomach, liver, and intestines.
   • Retroperitoneal: Kidneys, pancreas, and adrenal glands.
