The mesothelium is a membrane composed of simple squamous epithelial cells of mesodermal origin, [2] which forms the lining of several body cavities: the pleura (pleural cavity around the lungs), peritoneum (abdominopelvic cavity including the mesentery, omenta, falciform ligament and the perimetrium) and pericardium (around the heart).
Simple squamous epithelia are found in endothelium (lining of blood and lymph capillaries), mesothelium (coelomic epithelium/peritoneum), alveoli of lungs, glomeruli, and other tissues where rapid diffusion is required. [2]

Squamous epithelium is found lining surfaces such as skin or alveoli in the lung, enabling simple passive diffusion as also found in the alveolar epithelium in the lungs. Specialized squamous epithelium also forms the lining of cavities such as in blood vessels (as endothelium ), in the pericardium (as mesothelium ), and in other body cavities .
Each serous membrane is composed of a secretory epithelial layer and a connective tissue layer underneath. The epithelial layer , known as mesothelium , consists of a single layer of avascular flat nucleated cells ( simple squamous epithelium ) which produce the lubricating serous fluid.
Hypochlorous acid is a natural molecule in the body but can also be used in skincare. Experts share how it’s used and why it’s the latest buzzy ingredient.
Adopted by Gen Z and Gen Alpha, it gained new prominence in 2024, according to Oxford, as a term used to capture concerns about the impact of consuming excessive amounts of "low-quality online ...
A serous membrane is an epithelial membrane composed of mesodermally derived epithelium called the mesothelium that is supported by connective tissue. [2] These membranes line the coelomic cavities of the body, that is, those cavities that do not open to the outside, and they cover the organs located within those cavities.
