That is, they are located behind the smooth peritoneal lining of the upper part of the abdominal cavity, between it and the posterior body wall. Therefore, they are actually outside the peritoneal cavity.

Why are kidneys called retroperitoneal?

The kidneys are considered “retroperitoneal” organs, which means they sit behind a lining in the abdominal cavity, unlike all other abdominal organs.

Is the pancreas intraperitoneal or retroperitoneal?

What organ is primarily retroperitoneal?

  • The primary retroperitoneal structures are the adrenal glands, kidneys, ureters, inferior vena cava, and the rectum. Secondary retroperitoneal structures include the duodenum (except for the proximal first segment), the pancreas (head, neck and body), ascending colon, and descending colon.

Which organ is most likely intraperitoneal?

Intraperitoneal organs include the stomach, spleen, liver, first and fourth parts of the duodenum, jejunum, ileum, transverse, and sigmoid colon.

Why is ovary intraperitoneal?

Of all intraperitoneal organs, the ovary is the only one that is not delineated by peritoneum of the free abdominal cavity. Thus, during ovulation, the mature egg reaches the free abdominal space before getting swept in by the ciliated epithelium of the oviduct, arching over the ovary.

Are ovaries intra or retroperitoneal?

Although the ovary is considered an intraperitonal organ, it only has a peritoneal duplicate but its surface isn't covered by peritoneum.
