Pulmonary pleurae

Pulmonary Pleurae

The Pulmonary Pleurae are the two thin layers of tissue that protect and cushion the lungs. The pleurae are separated by a small amount of fluid, which allows the two layers to slide over each other easily during respiration.

Structure

The pulmonary pleurae consist of two layers: the visceral pleura and the parietal pleura. The visceral pleura is the inner layer that is attached to the lung tissue itself. The parietal pleura is the outer layer that lines the inside of the chest wall and diaphragm.

Function

The main function of the pulmonary pleurae is to protect the lungs from friction and other physical damage. The pleural fluid between the two layers allows them to slide smoothly over each other during respiration, preventing friction between the lungs and the chest wall.

Diseases and Conditions

There are several diseases and conditions that can affect the pulmonary pleurae, including pleurisy, pleural effusion, and mesothelioma. Pleurisy is inflammation of the pleurae, which can cause sharp chest pain during breathing. Pleural effusion is a condition where excess fluid builds up in the pleural space. Mesothelioma is a type of cancer that develops in the pleurae.

Treatment

Treatment for diseases and conditions of the pulmonary pleurae depends on the specific condition and its severity. Treatment options may include medication, surgery, or other procedures to remove fluid or air from the pleural space.
