The double-walled membrane that produces watery fluids is called the serous membrane. It lines certain cavities in the body and secretes a lubricating fluid to reduce friction between organs.
The double-layered membrane on the outside of the heart is called the pericardium. It consists of two layers: the outer fibrous pericardium, which provides protection and support, and the inner serous pericardium, which is further divided into the parietal layer and the visceral layer (or epicardium). The serous fluid between these layers reduces friction as the heart beats, allowing for smooth movement. This structure plays a crucial role in protecting the heart and maintaining its position within the thoracic cavity.
Mitochondria are the only organelle in a cell which is surrounded by a double layered membrane. Also chloroplast in plants are surrounded by double layered membrane.
The pericardial sac is lined with a double-layered membrane called the serous pericardium. The inner layer is the visceral pericardium (or epicardium) which is in contact with the heart, and the outer layer is the parietal pericardium which is attached to the surrounding structures.
Serous fluid is a clear, watery substance that is secreted by serous membranes, which are thin, double-layered membranes that line body cavities and internal organs. These membranes produce serous fluid to lubricate and reduce friction between tissues during movement.
the peritoneum, pleura, and pericardium
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 peritoneum is the double-layered serous membrane that supports the viscera in the abdominal cavity. It consists of both parietal (lining the abdominal wall) and visceral (covering the organs) layers. These layers secrete fluid to reduce friction and allow the organs to move smoothly.

Pleura is a double layered membrane surrounding each lung.
Pleura is a double layered membrane surrounding each lung.
Serosa is the medical term meaning serous membrane."serous membrane" and "the serous membrane"

This structure plays a crucial role in protecting the heart and maintaining its position within the thoracic cavity.
The outer layer of the serous membrane that covers each testis is called the tunica vaginalis. It is a two-layered structure that surrounds and protects the testis within the scrotum.
