PLEURA Meaning and
Definition
-
The pleura is a noun that refers to a thin, membranous tissue that lines the chest cavity and covers the lungs. It is composed of two layers: the visceral pleura and the parietal pleura.
The visceral pleura is the inner layer, tightly adhering to the surface of the lungs and covering their external surface. Meanwhile, the parietal pleura is the outer layer that lines the walls of the chest cavity. These two layers are separated by a small space known as the pleural cavity, which is filled with a small amount of pleural fluid that helps reduce friction during breathing.
The main function of the pleura is to protect and support the lungs, allowing them to expand and contract during respiration. It acts as a watertight seal between the lungs and the chest wall, ensuring that any changes in pressure do not cause air or other substances to enter the pleural cavity.
Pleural conditions such as pleurisy, pleural effusion, and pneumothorax can cause inflammation, infection, or the accumulation of fluid or air in the pleural space, leading to respiratory difficulties and discomfort. Various diagnostic tests, including chest X-rays and ultrasounds, can help identify abnormalities in the pleura.
In summary, the pleura is a vital component of the respiratory system, providing a protective and lubricating surface for the lungs to expand and contract within the chest cavity.
