Pleura of the Lungs

Pleura of the Lungs

The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Pleural Effusion I: Introduction

Pleural Effusion I: Introduction

Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.
There are two main types of pleural effusion: transudative and exudative. They are differentiated using Light's criteria,...

Pneumothorax II: Pathophysiology

Pneumothorax II: Pathophysiology

Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...

Pleural Disorders: Types and Brief Description

Pleural Disorders: Types and Brief Description

The pleura is a vital part of the respiratory system. It's a double-layered membrane surrounding the lungs and lining the chest cavity. The two layers of the pleura are:

Pleural Effusion II: Symptoms and Management

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Main Results:

Extensive research exists on CNT effects on lungs, but limited data is available for the pleura.
Animal and in vitro studies provide preliminary insights into CNT-pleura interactions.
A significant gap in understanding CNTs' specific pleural toxicity is evident.

Conclusions:

Further research is crucial to understand the effects of carbon nanotubes on the pleura.
More animal and in vitro studies are needed to elucidate CNT-pleura interactions.
Comprehensive data is required to assess the safety of CNTs concerning pleural health.
