Mesotelioepiteeliä

Mesotelioepiteeliä refers to the mesothelium, a serous membrane that forms the lining of several body cavities, including the pleura (lining the thoracic cavity), pericardium (lining the heart cavity), and peritoneum (lining the abdominal cavity). It is a single layer of flattened squamous cells called mesothelial cells. This delicate tissue plays a crucial role in lubrication, allowing organs to move freely within their respective cavities without friction. For example, the mesothelium covering the lungs produces a thin layer of fluid that facilitates smooth breathing movements.

The mesothelium is derived from the embryonic mesoderm. Its primary functions include protection, secretion of lubricating fluid, and absorption. The mesothelial cells are characterized by their smooth surface, which minimizes friction. In certain pathological conditions, such as inflammation or exposure to asbestos, these cells can undergo changes, leading to conditions like mesothelioma, a rare and aggressive cancer. Diagnosis and treatment of conditions involving the mesothelium often require specialized medical expertise. Understanding the structure and function of mesotelioepiteeliä is important in the context of various medical fields, particularly oncology and respiratory medicine.
