Pronunciation:
pare i toe NEE um • (noun)
Common Misspellings:
paritoneum
Definition:
A membrane which lines the abdominal and pelvic cavities, and covers most of the
internal organs there. The membrane has two parts: the parietal peritoneum is
the part which is closest to the pelvic and abdominal walls (underneath the abdominal
muscles and fat layers), and the visceral peritoneum, which is the part that covers
the organs. In between, the peritoneum makes fluid so that all these surfaces
can slide easily over one another.
