What is the difference between peritoneum and omentum?

The main difference between omentum and peritoneum is that omentum is an abdominal structure formed from the visceral peritoneum with a structure similar to the mesentery whereas peritoneum is the thin, serosal membrane, which lines the abdominal and pelvic cavities, covering most of the viscera.

What are the four layers of the greater omentum?

The greater omentum is also known as the great omentum, the omentum majus, the gastrocolic omentum, the epiploon, and the caul.

What is the difference between peritoneum and peritoneal?

The peritoneum can be considered as a kind of balloon or sac that is inflated inside the abdomen and lines the inside of the abdominal wall. The peritoneum encloses a cavity: the peritoneal cavity. The peritoneal cavity forms roughly half the (anterior to posterior) depth of the abdomen.
