Iseoluwa, say the vertical tracing of the peritoneum And difference in male and females own

Peritoneum from anterior abdominal wall lines the anterior and posterior surface of liver except bare area. Anterior and posterior layers form anterior and posterior layers of lesser omentum extending from liver to lesser curvature of stomach. Anterior layer then covers anterior surface of stomach and then forms anterior layer of greater omentum (first layer of greater omentum) then becomes fourth layer of greater omentum. Posterior layer lines posterior surface of stomach and forms second and third layer of greater omentum passes around the anterior surface of transverse colon and then lines upper part of posterior abdominal wall. Anterior layer then passes around the colon to become its posterior layer. Lines posterior abdominal wall. It is reflected anteriorly as anterior layer of mesentery then passes around small intestine to become posterior layer. It lines the posterior abdominal wall and descends into the pelvis In females, it passes in front of rectum and uterus forming rectouterine pouch and from uterus to urinary bladder forming vesicouterine pouch. In males, it passes in front of rectum to urinary bladder and forms rectovesical pouch Peritoneum then passes from urinary bladder to anterior abdominal wall
