What is the Intrapleural space?
The pleural cavity, also known as the intrapleural space, contains pleural fluid secreted by the mesothelial cells. The fluid allows the layers to glide over each other as the lungs inflate and deflate during respiration.
What happens when the pleural space is disrupted?
The negative pressure of the pleural cavity acts as a suction to keep the lungs from collapsing. Damage to the pleura could disrupt this system, resulting in a pneumothorax.
What is the purpose of the Costodiaphragmatic and Costomediastinal recess?
It assists lung expansion during deep inspiration, although its role is not as significant as the costodiaphragmatic recess, which has a greater volume. The lung expands into the costomediastinal recess even during shallow inspiration….

What is normal pleural space?
In a healthy human, the pleural space contains a small amount of fluid (about 10 to 20 mL), with a low protein concentration (less than 1.5 g/dL). Pleural fluid is filtered at the parietal pleural level from systemic microvessels to the extrapleural interstitium and into the pleural space down a pressure gradient.
Is the intrapleural space between the heart and lungs?
The thoracic cavity is the space that includes the pleura, lungs, and heart, while the pleural space is only the space between the Parietal pleura and visceral pleura surrounding lungs. Intrapleural pressure depends on the ventilation phase, atmospheric pressure, and the volume of the intrapleural cavity.
What is the intrapleural space What happens if air is introduced into the intrapleural space?
This allows atmospheric air to enter the pleural space, which causes the intrapleural pressure to rise toward atmospheric pressure and produces pneumothorax and collapse of the lung.
What is the purpose of the pleural space?
The pleural cavity aids optimal functioning of the lugs during breathing. It transmits movements of the chest wall to the lungs, particularly during heavy breathing. The closely approved chest wall transmits pressures to the visceral pleural surface and hence to the lung (10-19).
What is pleural space in lungs?
Definition: pleural space. Also called pleural cavity. The cavity that exists between the lungs and underneath the chest wall. It is normally empty, with the lung immediately against the inside of the chest wall.
What is costo diaphragmatic recess?
The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, is the posterolateral fringe of the pleural space, a potential space around the lung inside the pleural cavity.
Is the costomediastinal recess bilateral?
They are present bilaterally at expiration and fill in with lung during inspiration and include the anterior and posterior costomediastinal recess, costophrenic recess, and mediastinophrenic recess 1 , 4 (Fig.
What is the pleural space in the lungs?
What fluid is in the pleural space?
Pleural fluid is a serous fluid produced by the serous membrane covering normal pleurae. Most fluid is produced by the exudation in parietal circulation (intercostal arteries) via bulk flow and reabsorbed by the lymphatic system.
