 The parietal peritoneum lines the abdominal walls; undersurface of the diaphragm;
anterior surface of the retroperitoneal viscera and the pelvis.12The peritoneum subdivided into interconnected
compartments by the peritoneal ligaments and mesenteries which determine the location and routes of spread of
primary and secondary malignancies and infection within the peritoneal cavity.Normally a very small volume of
sterile fluid is present in the peritoneal cavity.This fluid continuously circulates upwards to the subdiaphragmatic
spaces where the subphrenic submesothelial lymphatics provide most of the lymphatic clearance from the peritoneal
cavity.
