The abdominopelvic cavity is lined v a serous membrane dubbed the peritoneum. This membrane increases from the interior surface of the abdominal wall to completely or partially surround offal 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 currently the inner walls the the abdominal muscle cavity, developing a close up door sac recognized as the peritoneal cavity. The peritoneal cavity is completely closed in males. In females, the peritoneal cavity has actually two openings whereby the uterine tubes, uterus, and also vagina provide a passage to the outside. The parietal peritoneum mirrors off of the posterior ab wall, creating a fused, twin layer the peritoneum neighboring the blood vessels, nerves, and lymphatics to abdominal organs. This twin layer of peritoneum, known as the mesentery, suspends the jejunum and ileum native the posterior ab wall. The peritoneum the surrounds the gut tube is referred to as the visceral peritoneum. The peritoneal membranes produce a serous fluid that lubricates the peritoneal surfaces, enabling the intraperitoneal organs come slide across one one more with minimal friction.
