Peritonitis is an inflammation (irritation) of the peritoneum. This is the thin tissue that lines the inner wall of the abdomen and covers most of the abdominal organs. Peritonitis is caused by a collection of blood, body fluids, or pus in the belly (abdomen). One type is called spontaneous bacterial peritonitis (SPP). It occurs in people with ascites. Ascites is the buildup of fluid in the space between the lining of the abdomen and the organs.

Add to Trip. While any measurement of the exact center of the United States will always be imprecise for a number of reasons, due to such factors as the exact placement of thousands of miles of changing shoreline, the U.S. National Geodetic Survey (NGS) has produced designated coordinates for the center of the United States.
