Intraperitoneal organs are located inside the peritoneal cavity and are fully covered by visceral peritoneum, often suspended by mesenteries or ligaments. The stomach and liver fit this description because both are enveloped by peritoneum and connected to the abdominal walls and each other by structures like the omenta and ligaments (the stomach via the greater and lesser omenta; the liver via the falciform, coronary, and other peritoneal ligaments). This arrangement makes them mobile within the cavity and reflects why they’re classified as intraperitoneal. They are not retroperitoneal, which would mean they lie against the posterior abdominal wall with only partial peritoneal covering, nor are they extraperitoneal or subperitoneal, terms that describe structures outside or beneath the peritoneal lining.
