The serous membrane that lines the wall of body cavities is called the parietal serosa. This membrane surrounds organs and helps to reduce friction between them and the walls of the cavity.
Blood vessels are surrounded by smooth muscle. This is often known as visceral muscle. This type of muscle also lines the blood vessels and internal organs.
The epithelium that lines the body cavities is known as mesothelium. Mesothelial cells form a protective layer over internal organs and body cavities, providing lubrication and support for organs to move smoothly against each other.
Endothelium is a type of epithelium that lines blood vessels and the heart, while mesothelium is a type of epithelium that lines body cavities such as the abdominal and thoracic cavities. Endothelium helps regulate exchange of substances between blood and surrounding tissues, while mesothelium mainly provides a protective barrier and lubrication for organs within body cavities.
A serous membrane lines the body cavities and also covers the organs inside the cavities. The upper cells produce the lubricating serous fluid. This fluid has a consistency similar to thin mucus. There is a connective tissue layer that provides the blood vessels and nerves for the overlying secretory cells, and also serves as the binding layer which allows the whole serous membrane to adhere to organs and other structures.
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.
Serous membranes line body cavities that do not open to the outside and secrete a lubricating fluid that reduces friction between organs and allows them to move smoothly. They also provide a protective barrier against infection and help maintain the integrity of the internal organs.
Epithelial tissue lines bodily cavities/surfaces.
Cardiac, smooth and skeletal.
The peritoneal sac in animals is a serous membrane that lines the abdominal and pelvic cavities. It acts to support and protect the organs within these cavities, as well as provide lubrication for their movement.
The epithelium that lines the body cavity is called mesothelium. It consists of a layer of flat cells called mesothelial cells that form a protective covering over organs in the body cavities.
Serous tissue is a thin, smooth membrane that lines the cavities of various body structures, such as the abdomen and chest. It produces a fluid called serous fluid that helps reduce friction between organs and allows them to move smoothly.
