Medical Definition of peritoneal cavity. : a space formed when the parietal and visceral layers of the peritoneum spread apart.
Peritonitis is inflammation of the peritoneal cavity. It is very painful and almost always signals a very serious or life-threatening disorder. It can result from any abdominal problem in which the organs are inflamed or infected. Common examples include appendicitis, diverticulitis, and pancreatitis. Also, blood and body fluids (such as intestinal contents or urine) are very irritating when they leak into the peritoneal cavity and can cause peritonitis.
