Question

The __________ is the serous membrane that lines the abdominal organs.

Answer 1

The peritoneum is the serous membrane lining the abdominal organs, composed of a parietal layer lining the abdominal wall and a visceral layer covering the organs, with serous fluid in between.

Step-by-step explanation:

The peritoneum is the serous membrane that lines the abdominal organs. This membrane is a continuous sheet that forms both the parietal peritoneum, lining the abdominal wall, and the visceral peritoneum that envelops the abdominal organs, creating a fluid-filled space called the peritoneal cavity.

This cavity is filled with a small amount of lubricating serous fluid that reduces friction between the organs as they move, protecting them from inflammation and damage. In the digestive system, the peritoneum supports the organs and forms double sheets of mesenteries that suspend many of the digestive organs.

Answer 2

The description above refers to parietal peritoneum. The parietal peritoneum is referred to as the serous membrane that borders the organs in the abdomen as well as the pelvic cavities. The peritoneum is classified into two and the other is known as the visceral peritoneum which covers the external surfaces.
