Peritoneum with drainage labelled – image description

This illustration shows a side view of a woman's tummy, also called the abdomen. She is facing to the left with her spine showing on the right-hand side. It shows the internal organs and the peritoneum, which is a membrane inside the abdomen that has two layers. One layer lines the wall of the tummy and the other covers the internal organs. The illustration shows that fluid has built up between the two layers of the peritoneum. A thin tube has been inserted into her tummy between the two layers of the peritoneum and fluid is shown draining through this tube into a drainage bag outside her body.
