*The peritoneum is smooth and clear in the healthy animal.
*It consists of a thin layer of loose connective tissue covered by a single layer of [[Mesothelial cells|mesothelial cells]].
*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.
*There are two layers of peritoneum lining the abdomen.
**The layer in contact with the abdominal wall
*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.''
