The abdominopelvic cavity is lined v a serous membrane dubbed the peritoneum. This membrane broadens from the internal surface of the abdominal wall to fully or partly surround organs of the abdominopelvic cavities.

The peritoneum is a serous membrane that is composed of two layers: parietal peritoneum and also visceral peritoneum (Figure 8-1A–C). The parietal peritoneum present the inner walls of the abdominal cavity, developing a close up door sac recognized as the peritoneal cavity. The peritoneal cavity is fully closed in males. In females, the peritoneal cavity has actually two openings wherein the uterine tubes, uterus, and vagina carry out a passage to the outside. The parietal peritoneum reflects off that the posterior abdominal wall, forming a fused, twin layer of peritoneum surrounding the blood vessels, nerves, and also lymphatics to ab organs. This dual layer of peritoneum, known as the mesentery, suspends the jejunum and ileum from the posterior abdominal wall. The peritoneum that surrounds the gut tube is called the visceral peritoneum. The peritoneal membranes create a serous liquid that lubricates the peritoneal surfaces, allowing the intraperitoneal organs come slide across one an additional with minimal friction.
