Pleural refers to anything related to the pleura, the thin, moist, double-layered membrane that surrounds the lungs and lines the inside of the chest cavity. The pleura produces a lubricating fluid that allows the lungs to expand and contract smoothly during respiration.

Anatomy[edit | edit source]

The pleura consists of two layers: the visceral pleura, which adheres to the surface of the lungs, and the parietal pleura, which lines the chest wall and diaphragm. The space between these two layers is known as the pleural cavity, which contains a small amount of pleural fluid.

Function[edit | edit source]

The primary function of the pleura is to aid in the mechanics of breathing. The pleural fluid within the pleural cavity allows the two layers of the pleura to slide against each other without friction, enabling the lungs to expand and contract smoothly during respiration. The pleura also helps to maintain the position of the lungs within the chest cavity.

Pleural Disorders[edit | edit source]

There are several disorders that can affect the pleura, including pleurisy, pleural effusion, and pleural mesothelioma. Pleurisy is an inflammation of the pleura that can cause sharp chest pain. Pleural effusion is a condition in which excess fluid builds up in the pleural cavity. Pleural mesothelioma is a rare form of cancer that develops in the cells of the pleura, often due to exposure to asbestos.
