The stomach has 2 peritoneal folds attached to each of the stomach curvatures. The greater omentum is the peritoneal fold extending from the greater curvature of the stomach to the colon, and hanging down over the small intestine. The lesser omentum is the peritoneal fold extending from lesser curvature of the stomach to liver. ( More? GIT Notes)
