sow's peritoneum

The abdominal cavity holds the bulk of the viscera. It is lined with a protective membrane termed the peritoneum. The front of the viscera is covered with a layer of peritoneum called the greater omentum.

The peritoneum is a thin, translucent membrane that covers the internal abdominal body wall and the abdominal organs. The visceral peritoneum is the part of the peritoneum that is adhered to the visceral (abdominal) organs such as the liver, stomach, intestines, etc. The rest of the peritoneum that is adhered to the body wall is called the parietal peritoneum.
