intraperitoneal

Examples of intraperitoneal in the following topics:

• The Peritoneum

  • Remember not to confuse the abdominal cavity with the intraperitoneal space, which is located within the abdominal cavity and wrapped in peritoneum tissue.
  • The inner layer, the visceral peritoneum, is wrapped around the internal organs that are located inside the intraperitoneal cavity.
  • The structures in the abdomen are classified as intraperitoneal, retroperitoneal, or infraperitoneal depending on whether they are covered with visceral peritoneum and are attached by mesenteries, such as the mensentery and mesocolon.
  • Other organs located in the intraperitoneal space are the liver, spleen, and the tail of the pancreas.
  • Structures that are intraperitoneal are generally mobile, while those that are retroperitoneal are relatively fixed in their location.

• Body Cavity Membranes

  • The peritoneum both supports the abdominal organs and serves as a conduit for their blood and lymph vessels and nerves.The abdominal cavity (the space bounded by the vertebrae, abdominal muscles, diaphragm and pelvic floor) should not be confused with the intraperitoneal space (located within the abdominal cavity, but wrapped in peritoneum).
  • The structures within the intraperitoneal space are called "intraperitoneal" (e.g. the stomach), the structures in the abdominal cavity that are located behind the intraperitoneal space are called "retroperitoneal" (e.g. the kidneys), and those structures below the intraperitoneal space are called "subperitoneal" or "infraperitoneal" (e.g. the bladder).

• Ovaries

  • The ovary is the only organ in the human body which is totally invaginated into the peritonium, making it the only intraperitoneal organ.
