PATHOLOGY

Detailed explanation-1: -The greater omentum (or omentum majus), as its name suggests, is the largest of the two omenta. It is an apron like structure that extends from the greater curvature of the stomach and proximal duodenum. From here, it descends inferiorly over the transverse colon, jejunum and ileum.

Detailed explanation-2: -The mesentery is a band of peritoneum that is attached to the wall of the abdomen and encloses the viscera. It extends from the pancreas, over the small intestine, and down over the colon and upper rectum.

Detailed explanation-3: -The greater omentum and lesser omentum are folds of peritoneum that drape from the stomach. The greater omentum extends to cover the transverse colon and the small bowel and serves to contain inflammation or tumor.
