*It consists of a thin layer of loose connective tissue covered by a single layer of [[Mesothelial cells|mesothelial cells]]. Collectively, the connective tissue and peritoneum are referred to as the '''serosa'''.

**Mesothelial cells are simple squamous and of mesodermal origin.
**Mesothelial cells are simple squamous and of mesodermal origin.
**A small amount of fibroelastic tissue is present within the connective tissue layer to provide support.
*There are two layers of peritoneum lining the abdomen.
*There are two layers of peritoneum lining the abdomen.
**The layer in contact with the abdominal wall
**The layer in contact with the abdominal wall is called the '''parietal layer'''.
**The layer covering the abdominal viscera is called the '''visceral layer'''.
**The small space within these two layers is called the '''peritoneal cavity'''.
*Many species have lymphoid tissue aggregates and fixed phagocytes in the omentum that are not covered by mesothelial cells

*''NB Post mortem change and autolysis result in increased volumes of red-brown fluid in the abdomen, not associated with other pathology, no roughening of surfaces of organs or peritoneum.''
