Pleur

Pleur is a term derived from the Greek word "pleura," which refers to the ribs and the chest wall. In medical terminology, it is often used to describe conditions or structures related to the pleura, the thin membrane that lines the lungs and the chest cavity. The pleura serves a crucial role in protecting the lungs and facilitating their movement during breathing.

The pleura is divided into two layers: the visceral pleura, which covers the outer surface of the lungs, and the parietal pleura, which lines the inner surface of the chest wall and diaphragm. Between these two layers lies a small amount of fluid, known as pleural fluid, which reduces friction and allows the lungs to slide smoothly against the chest wall during respiration.

Pleur can refer to several medical conditions, including:

1. Pleurisy: Inflammation of the pleura, often caused by infection or injury, which can result in chest pain and difficulty breathing.

2. Pneumothorax: A condition where air leaks into the pleural space, causing the lung to collapse.

3. Pleural effusion: The accumulation of excess fluid in the pleural space, which can lead to shortness of breath and reduced lung function.

Diagnosis of pleural conditions typically involves imaging techniques such as chest X-rays, CT scans, or ultrasound, as well as analysis of pleural fluid if necessary. Treatment options depend on the specific condition and may include rest, pain management, antibiotics, or surgical intervention.
