Albanese et al reported the various subparts of the peritoneum with the relative percentages. The authors are from Universidad del Salvador in Argentina.
Major parts:
(1) supracolic visceral peritoneum: 18.5%
(2) supracolic parietal peritoneum: 13.3%
(3) infracolic visceral peritoneum: 60.2%
(4) infracolic parietal peritoneum: 8.0%
