Serous membrane
A serous membrane also called the serosa is the type of membrane that lines cavities that do not open to the outside of the body.
The serous membrane, specifically the parietal layer, lines the subdivisions of the ventral body cavity. It is extremely delicate and is not directly connected to the exterior, serving to reduce friction between organs and the cavity walls.
The double membrane that covers the lungs and lines the thoracic cavity is called the pleura. It consists of two layers: the visceral pleura attached to the lungs and the parietal pleura lining the thoracic cavity. The pleura produces a small amount of fluid that helps reduce friction during breathing.
The serous membrane in the abdominopelvic cavity is called the peritoneum. It consists of two layers - the parietal peritoneum which lines the abdominal wall, and the visceral peritoneum which covers the organs within the abdominal cavity. The peritoneum produces a fluid that helps to reduce friction between organs during movement.
The term for organs that lie within the abdominal cavity but not within the peritoneal cavity is "retroperitoneal organs." These organs include the kidneys, adrenal glands, pancreas, and parts of the gastrointestinal tract. They are positioned behind the peritoneum, a membrane that lines the abdominal cavity.

The visceral peritoneum, a serious membrane, lines the outside of the small intestine where it meets the peritoneal cavity.
The endosteum lines the medullary cavity.

The tissue that lines the walls of the ventral cavity is called the serous membrane or mesothelium. This membrane consists of two layers: the parietal layer which lines the cavity walls, and the visceral layer which covers the organs within the cavity. The serous membrane produces a fluid that reduces friction between internal structures during movement.
The serous membrane, specifically the parietal serosa, lines the closed ventral cavities of the body. Examples include the pleura in the thoracic cavity and the peritoneum in the abdominal cavity.
