Mucous membranes
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).
The basic function of a Mesothelial cell is to act as a lining for body cavities. This type of cell helps seal fluids in these cavities and keep unwanted materials away.
The lining of the mouth is an example of a mucous membrane. Mucous membranes line various cavities in the body and produce mucus to protect and lubricate the underlying tissues.
Membranous epithelium is a type of tissue that consists of a single layer of epithelial cells resting on a basement membrane. It is mainly found lining body cavities and organs, where it serves a protective and absorptive function. Examples of membranous epithelium include the lining of the respiratory tract and the lining of blood vessels.
Ciliated epithelium is located in the lining of most body cavities. Some of the cavities that have ciliated epithelium are the lungs, trachea, and nose. Ciliated epithelium serves to keep dust and debris out of the lungs and control the flow of mucus.
Mucus
The main tissue in the skin and the lining of body cavities is epithelial tissue. Epithelial tissue serves as a protective barrier, helps with absorption and secretion, and is composed of tightly packed cells that form continuous sheets.
Mesothelium and endothelium are types of epithelium tissue. Mesothelium lines the body cavities and endothelium lines primarily the circulatory system.

The types of membranes lining cavities that communicate with the exterior of the body are mucous membranes. These membranes are found in areas such as the respiratory, digestive, urinary, and reproductive tracts, and they secrete mucus to protect and lubricate the tissues.

In the human body, the mesothelium membrane is involved in lining several body cavities, including the thoracic cavity, the abdominal cavity, and the heart sac.
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.
