- Pleural cavity - Structure, Function, Location, Diagram
The pleural cavity is the potential space between parietal and visceral pleura filled with lubricating fluid Region Thorax The negative intrapleural pressure generated within the pleural cavity during respiration is essential for drawing air into the lungs and keeping them adhered to the chest wall Pneumothorax: Air in the pleural
- Pleura | Radiology Reference Article | Radiopaedia. org
The visceral pleura remains roughly two ribs higher than the lines of pleural reflection in the lower thorax (e g visceral pleura crosses MAL at the level of the 8th rib) The surface markings of the lines of pleural reflection are important to know as an incision or puncture along these lines can inadvertently cause a pneumothorax or a haemothorax

The pleural cavity is a fluid filled space that surrounds the lungs It is found in the thorax, separating the lungs from its surrounding structures such as the thoracic cage and intercostal spaces, the mediastinum and the diaphragm The pleural cavity is bounded by a double layered serous membrane called pleura Pleura is formed by an inner visceral pleura and an outer parietal layer
- Pulmonary pressures – Basic Human Physiology
Intrapleural pressure is the pressure within the pleural cavity due to the fluid bond between the visceral and parietal pleura and the parietal pleura’s adhesion to the body wall and diaphragm Similar to intra-alveolar pressure, intrapleural pressure also changes during the different phases of breathing
- Pleural Anatomy, Physiology, and Imaging Modalities - ScienceDirect
The lungs are surrounded by layers of visceral and parietal pleura, which line the inner aspect of the thoracic cavity and form the boundaries of the pleural space 1 The pleura acts as a covering sheath which envelops the lung parenchyma, diaphragm and mediastinum 2 The visceral pleura forms the major, minor and accessory fissures, which are two invaginated sheets of the visceral pleura 3
- Pneumothorax | Thoracic Key
The lungs remain inflated within the thoracic cavity because the intrapleural pressure remains negative throughout the respiratory cycle • A pneumothorax occurs when air is allowed to enter through the chest wall or the lung, thereby connecting the pleural space to atmospheric pressure and removing the fixed negative intrathoracic pressure •
- Pathology Chapter 23: Pneumothorax Flashcards - Quizlet
Gas can gain entrance to the pleural space in three ways: 1 From the lungs through a perforation of the visceral pleura 2 From the surrounding atmosphere through a perforation of the chest wall and parietal pleura or, rarely, through an esophageal fistula or a perforated abdominal viscus 3 From gas-forming microorganisms in an empyema in the pleural space (rare)
- Ch. 5 The pleural space – Brians Radiology Learning Diary
– Pleural fluid is produced by the parietal pleura and reabsorbed by visceral pleura Intrapleural pressure diminishes ( e g lobar collapse ) 2 Exudate – In contrast to the well-defined sharp line limiting pneumothorax ( i e visceral pleura is smooth ), skin fold appears as a band of gradually increasing attenuation as it reaches
