Is the peritoneal cavity the same as the abdominal cavity?

The abdominal cavity is the open space surrounded by the vertebrae, abdominal muscles, diaphragm, and pelvic floor. Remember not to confuse the abdominal cavity with the intraperitoneal space, which is located within the abdominal cavity and wrapped in peritoneum tissue.

What is the peritoneum and its role in the abdominopelvic cavity?

What organs are in abdominopelvic cavity?

The peritoneal cavity is a theoretical space that exists between the two layers of the peritoneal mesothelium.

Is the pelvis part of the abdominal cavity?

What happens to the parietal peritoneum during intrauterine development?
