Lung Pleura (Anatomy) | Pleural Cavity | Overview
Показать описание
What are the lung pleura? This video covers the medical definition and provides a brief overview of this topic.
➡️ Structure of the Pleura
-- Visceral pleura: The visceral pleura is the innermost layer and covers the surface of the lungs.
-- Parietal pleura: The parietal pleura is the outermost layer and lines the inside of the chest wall.
These two layers are separated by a small amount of pleural fluid. The visceral pleura is closely adherent to the surface of the lungs and follows all of their contours, while the parietal pleura is separated from the lungs by the pleural cavity.
➡️ Function of the Pleura
The pleura play a crucial role in the process of breathing. During inhalation, the diaphragm contracts, and the chest expands. The pleural fluid reduces friction between the layers of pleura, allowing them to slide easily over one another during a breathing cycle. Exhalation occurs passively as the diaphragm relaxes and the chest wall returns to its resting position.
➡️ Disorders of the Pleura
Disorders of the pleura can affect the function of the respiratory system and lead to serious health problems.
➡️Types:
-- Pleurisy: A condition in which the pleura become inflamed, causing chest pain and difficulty breathing.
-- Pneumothorax: A condition in which air enters the pleural cavity, causing the lung to collapse.
-- Pleural effusion: A condition in which excess fluid accumulates in the pleural cavity, putting pressure on the lungs and making it difficult to breathe.
The treatment for these conditions depends on the underlying cause. Pleurisy may be treated with anti-inflammatory medications or antibiotics, while pneumothorax may require the insertion of a chest tube to remove the air from the pleural cavity. Pleural effusion may also require drainage of the fluid with a chest tube or thoracentesis. The pleural cavity is an essential component of the respiratory system, playing a crucial role in the process of breathing.
