Final answer:
The peritoneal cavity contains most of the digestive organs, and it is surrounded by the peritoneum membrane, answer D) peritoneal.
Step-by-step explanation:
Most of the digestive organs are contained within the peritoneal cavity, which is named for the membrane that surrounds it. The correct answer is D) peritoneal.
The peritoneum is the serous membrane that encloses the peritoneal cavity; this cavity surrounds several organs in the abdominopelvic cavity. The peritoneum consists of two layers: the parietal peritoneum which lines the abdominal wall, and the visceral peritoneum which envelops the abdominal organs. The space between these layers, known as the peritoneal cavity, is filled with a small amount of fluid that acts as a lubricant to minimize friction and allows the organs to move smoothly as they function.
