Peritoneum (noun)

The thin serous membrane that lines the abdominal cavity and surrounds the abdominal organs in mammals.

Origin:

From new latin, from greek peritonaion 'the membrane around the abdomen'.

Examples:

  1. The peritoneum serves to protect and support the abdominal organs, and to prevent friction and adhesions between them.
  2. Inflammation or injury to the peritoneum can result in abdominal pain, swelling, and other symptoms.
  3. Surgeons must be careful not to damage the peritoneum during abdominal surgeries, such as hernia repairs or appendectomies.
  4. The peritoneum is a crucial component of the body's defense against infections and diseases, and acts as a barrier to prevent the spread of germs.
  5. In peritoneal dialysis, a solution is infused into the peritoneum to remove waste products from the bloodstream, making it a lifesaving treatment for patients with kidney failure.
