What is the difference between peritoneum and omentum?

The peritoneum is a serous membrane that lines the abdomino-pelvic cavity and supports and protects abdominal organs. Omentum, on the other hand, is a fold of the peritoneum. Omenta form connections between the stomach and the duodenum. Peritoneum divides further as the visceral peritoneum and the parietal peritoneum.
