What are organs housed in the fibrous membrane within the abdominal cavity called?

Intraperitoneal organs are those that are suspended within the peritoneal cavity, which is a potential space lined by a fibrous membrane known as the peritoneum. This membrane serves to support the organs and allows for the movement and expansion of the digestive organs as they function. Examples of intraperitoneal organs include the stomach, liver, and the majority of the intestines.

Retroperitoneal organs are located behind the peritoneum and are not surrounded by the peritoneal cavity, which differentiates them from intraperitoneal organs. Subperitoneal organs are located below the peritoneum and, like retroperitoneal organs, are not freely suspended in the abdominal cavity. Pericardial organs refer to structures within the pericardial sac surrounding the heart and are unrelated to the abdominal cavity.

This context highlights the unique positioning of intraperitoneal organs and their relationship to the peritoneum, confirming why this designation is essential in understanding abdominal anatomy and physiology.
