The peritoneum
helps support the organs in the abdominal cavity
and also allows nerves, blood vessels, and lymph vessels to pass through to the organs. The parietal peritoneum lines the abdominal wall and extends to the organs, whereas the visceral peritoneum covers the organs.
What does parietal peritoneum do?
The parietal peritoneum
lines the internal surface of the abdominopelvic wall
. It is derived from somatic mesoderm in the embryo. It receives the same somatic nerve supply as the region of the abdominal wall that it lines; therefore, pain from the parietal peritoneum is well localised.
What is the function of the parietal peritoneum quizlet?
The peritoneum is a multilayered membrane that
protects and holds the organs in place within the abdominal cavity

, but it may also result from other irritants, such as foreign bodies, bile from a perforated gall bladder or a lacerated liver, or gastric acid from a perforated ulcer.
Can you remove the peritoneum?
If surgery is possible, the operation is called a
peritonectomy
. This means removing part or all of the lining of the abdomen (peritoneum).

outside the peritoneal cavity
.
What is the difference between peritoneum and perineum?
As nouns the difference between peritoneum and perineum
is that peritoneum is (anatomy) in mammals, the serous membrane lining the cavity of the abdomen and that
