Peritoneum
Your peritoneum is a multiple layered serous membrane that lines the abdominal cavity. Its inner layer is referred to as the visceral peritoneum, which wraps around most of your abdominal organs. But does not encase them all. Parietal peritoneum is the outer layer, which attach to the wall of the abdomen.
Inflammation of your peritoneum is known as peritonitis. And cancer can develop in this membrane, yet it rarely does.
Peritoneal Cavity
The space between the peritoneum layers is called the peritoneal cavity. Normally, it is filled with a small amount of serous fluid. This fluid acts as a lubricant and is slippery, so the layers can slide freely past one another.
Should excess fluid accumulate in the peritoneal cavity the health condition is known as ascites. This cavity can be used as waste removal site for blood in dialysis treatment.
