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.

Climate zones of the Contiguous United States. The climate of the United States varies due to differences in latitude, and a range of geographic features, including mountains and deserts. West of the 100th meridian, much of the US is semi-arid to arid, even desert in the far southwestern US.ake-effect snows add to precipitation potential downwind of the Great Lakes, as well as Great Salt Lake and the Finger Lakes during the cold season. The average snow to liquid ratio across the contiguous United States is 13:1, meaning 13 inches (330 mm) of snow melts down to 1 inch (25 mm) of water.
