What are the secondary retroperitoneal organs?
The ascending and descending colon and the duodenum and pancreas are secondary retroperitoneal organs. The ascending and descending colon are directly visible after one opens the peritoneal cavity, but they are fixed to the back wall, thus they are not mobile.
.
Furthermore, what are the retroperitoneal organs?
The intraperitoneal organs are the stomach, spleen, liver, bulb of the duodenum, jejunum, ileum, transverse colon, and sigmoid colon. The retroperitoneal organs are the remainder of the duodenum, the cecum and ascending colon, the descending colon, the pancreas, and the kidneys.
what is primary retroperitoneal? Retroperitoneal structures: These are structures which contain peritoneum only on their anterior surfaces. There are two types of retroperitoneal organs: Primary retroperitoneal and Secondary retroperitoneal. Primary retroperitoneal: These are structures which are retroperitoneal from the start of their development.
Consequently, what is the difference between primary and secondary retroperitoneal?
One sees the differences between the intraperitoneal structures which are well accessible and mobile, the secondary retroperitoneal structures which are accessible but fixed and the primary retroperitoneal structures, which are not even visible in an opened peritoneal cavity.
Where is the Retroperitoneum located in the body?
The retroperitoneum is an anatomical space located behind the abdominal or peritoneal cavity. Abdominal organs that are not suspended by the mesentery and lie between the abdominal wall and parietal peritoneum are said to lie within the retroperitoneum.

Omenta are abdominal structures formed from peritoneum and structurally similar to mesentery. The greater omentum is given off from the greater curvature of the stomach, forms a large sheet that lies over the intestines, then converges into parietal peritoneum.Why is omentum called abdominal policeman?
Because it has a phagocytic activity. It limits the spread of intraperitoneal infection and contains intraperitoneal infection. In 1906 Rutherford Morrison (Brit Med J1:76, 1906) coined the term, "the abdominal policeman," referring to the greater omentum.What is Paracolic gutter?
