Peritoneum
Peritoneum · Pobřišnice
Fascia & connective tissue
Looks like
A thin, glistening sheet lining the inside of the belly wall and wrapping most of the gut, with a film of fluid between its layers.
What it does
Lets the organs slide over each other and carries their vessels and nerves.
Keeping it well
Infection or a burst organ inflames it (peritonitis): a rigid belly with pain worse on any movement is an emergency.
