The serous membrane is composed of 2 thin linings. The inter lining, which directly covers the organ, is called the visceral membrane. Over the visceral is the parietal membrane. In between the two is a cushioning fluid.
The serous membrane resembles a balloon (visceral) inside another balloon (parietal) with fluid between them.
serous membrane
simple squamous
The lining of serous body cavities is formed by a membrane called the serosa, which consists of a layer of mesothelium (a type of simple squamous epithelium) and a supporting layer of connective tissue. This membrane produces serous fluid, which reduces friction between the organs and the cavity walls. Serous membranes are found in cavities such as the pleura (lungs), peritoneum (abdominal cavity), and pericardium (heart).
Serous membranes line body cavities that do not open directly to the outside, and they cover the organs located in those cavities. Serous membranes are covered by a thin layer of serous fluid that is secreted by the epithelium. Serous fluid lubricates the membrane and reduces friction and abrasion when organs in the thoracic or abdominopelvic cavity move against each other or the cavity wall. Serous membranes have special names given according to their location. For example, the serous membrane that lines the thoracic cavity and covers the lungs is called pleura.
Visceral serous membranes line organs. Parietal serous membranes line cavities.
simple squamus epithelium
serous membrane
The simple squamous epithelium forming the mesothelium of serous membranes helps to reduce friction between organs by serving as a smooth, protective barrier. It also allows for the easy movement of organs within body cavities.
Endothelium provides a slick, friction-reducing lining in lymphatic vessels and in all hollow organs of the cardiovascular system- blood vessels and the heart. Mesothelium is the epithelium found in serous membranes, the membranes lining the ventral body cavity and covering its organs.

Serous membranes are found in cavities such as the pleura (lungs), peritoneum (abdominal cavity), and pericardium (heart).
These are usually simple squamous epithelial cells. The epithelium lining the body cavities is called the mesothelium and is where the cancer mesothelioma arises from. The epithelium lining arteries and veins is called endothelium.
Simple squamous epithelium is the type of epithelial tissue that typically occurs in the facing layers of serous membranes. It is well-suited for allowing transport of fluids and gases across the membrane due to its thin and permeable nature.
The visceral segment of the serous membranes encases the internal organs while the parietal segment is responsible for lining the body wall. Serous membranes which care for the needs of the lungs are known as pleurae while the serous membranes which care for the abdominal cavity are known as peritoneum, but are also referred to as peritoneal membranes.
Pleura are examples of serous membranes, which are thin membranes that line body cavities not directly open to the outside of the body. They consist of two layers - parietal (lining the cavity walls) and visceral (covering the organs).
