**The layer covering the abdominal viscera is called the '''visceral layer'''.
**The layer covering the abdominal viscera is called the '''visceral layer'''.
**The small space within these two layers is called the '''peritoneal cavity'''.
**The small space within these two layers is called the '''peritoneal cavity'''.
**''NB: In reality there are no viscera located in the peritoneal cavity. However the cavity created by the '''serosa''' is also confusingly referred to as the peritoneal cavity, which contains most abdominal contents.''

*The peritoneum evaginates to extend into the inguinal canals.
*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.''
