Content: Generally, elements of the gastrointestinal tract and its derivatives completely fill the abdominal cavity, making the peritoneal cavity a potential space, and visceral peritoneum on organs and parietal peritoneum on the adjacent abdominal wall slide freely against one another. Abdominal viscera are either intraperitoneal or retroperitoneal: Intraperitoneal structures, such as elements of the gastrointestinal system, are suspended from the abdominal wall by mesenteries
Structures that are not suspended in the abdominal cavity by a mesentery and that lie between the parietal peritoneum and abdominal wall are retroperitoneal in position
Retroperitoneal structures include the kidneys and ureters, which develop in the region between the peritoneum and the abdominal wall and remain in this position in the adult. During development, some organs, such as parts of the small and large intestines, are suspended initially in the abdominal cavity by a mesentery, and later become retroperitoneal secondarily by fusing with the abdominal wall. Boundaries
The abdomen is defined as a part of trunk that lies between the diaphragm above and the pelvic inlet below. The boundaries of the abdominal cavity are as follows: Roof: It is formed by the diaphragm, which also forms the upper parts of the lateral and posterior walls. Anterior wall: It is made by three pairs of flat muscles (external oblique, internal oblique, and transversus abdominis) and their aponeuroses, and a pair of vertical muscles (rectus abdominis).
