They are called pleura. There are 2 membranes, the visceral which is the outer slippery covering, and the parietal which is the inner covering, with a cavity in between them called the pleural cavity
The pleura, a membrane that surrounds the lungs, produces a lubricating fluid called pleural fluid. This fluid reduces friction between the lungs and the chest wall when the lungs expand and contract during breathing.

The serous membrane has parietal and visceral layers. The parietal layer lines the body cavity, while the visceral layer surrounds and covers internal organs. This double-layered structure reduces friction as organs move within the body.
The membrane you are referring to is likely the serous membrane, which lines body cavities and surrounds organs. It consists of a parietal layer that lines the cavity wall and a visceral layer that covers the organ. These layers secrete a fluid that reduces friction between organs during movement.
The peritoneal cavity surrounds the digestive organs in the abdominal cavity. This cavity is lined by a serous membrane called the peritoneum, which helps support and protect the abdominal organs. It contains fluid that reduces friction between the organs during movement.
The visceral membrane is a type of serous membrane, which covers the outer layer of organs (such as the intestines). It secretes small amounts of a serous fluid, which reduces friction between organs and other structures.
The lubrication provided by a serous membrane helps to reduce friction between organs and body structures, allowing them to move smoothly against each other. This reduces wear and tear on tissues and minimizes the risk of inflammation or injury. Serous fluid also helps to maintain the integrity and function of organs within body cavities.
The synovial membrane is found in slightly movable joints, like the knee, hip, or shoulder joints. It helps to produce synovial fluid, which lubricates the joint and reduces friction between the articulating surfaces during movement. In immovable joints, like the skull sutures, the need for a synovial membrane is not present as these joints do not move.
The smooth cartilage that surrounds the surface of bones at joints is called articular cartilage. It acts as a cushion and reduces friction between bones during movement, helping to facilitate smooth joint motion.
The serous membrane, also known as serosa, provides lubrication to the pleural, pericardial, and peritoneal cavities. This membrane secretes a fluid called serous fluid, which reduces friction between organs as they move within these cavities.
