Peritoneum with drainage labelled – image description

The illustration shows a side view of the body. The peritoneum covers the outside of the organs that are inside the abdomen. There is a lot of fluid inside the peritoneum stretching the tummy so it looks swollen. A needle has been put through the skin of the tummy so that its tip is sitting in the fluid. The part of the needle outside the body is connected to tubing that leads into a drainage bag. Fluid from the peritoneum is draining through the tubing into the bag.
