- peritoneal
- mucous
- serous
- abdominal

Answer 1

The abdominal cavity is a potential space where the parietal and visceral layers of the peritoneum secrete a lubricating serous fluid.

Step-by-step explanation:

The abdominal cavity is a potential space where the parietal and visceral layers of the peritoneum secrete a lubricating serous fluid. The peritoneum is a broad serous membranous sac made up of squamous epithelial tissue surrounded by connective tissue. It consists of two regions: the parietal peritoneum, which lines the abdominal wall, and the visceral peritoneum, which envelopes the abdominal organs. The serous fluid acts as a lubricant to minimize friction between the serosal surfaces of the peritoneum.
