Which type of peritoneum lines the abdominal cavity?

The type of peritoneum that lines the abdominal cavity is the parietal peritoneum. This membrane serves a vital function by acting as a protective layer that covers the interior walls of the abdominal cavity, providing a smooth surface that allows for the movement of abdominal organs without friction.

In contrast, the visceral peritoneum tightly envelops the organs within the abdominal cavity, offering protection and support to those organs. The distinction between these two types of peritoneum is crucial for understanding their respective roles in the anatomy of the abdominal cavity.

Skeletal peritoneum and adventitial peritoneum are not recognized terms in human anatomy related to the peritoneum, further emphasizing the importance of the parietal and visceral classifications in this context. The parietal peritoneum's anatomical positioning and function are what establish it as the correct answer in this scenario.
