The fluid between the lung and chest wall helps the lungs expand and contract smoothly during breathing. It acts as a lubricant, reducing friction and allowing the lungs to move easily within the chest cavity. This fluid also helps maintain the pressure balance between the lungs and chest wall, which is important for efficient breathing.
The fluid between the lungs and chest wall can affect respiratory function by making it harder for the lungs to expand and contract properly. This can lead to difficulty breathing and decreased oxygen exchange in the body.
The pleura, a membrane that surrounds the lungs, produces a lubricating fluid called pleural fluid. This fluid reduces friction between the lungs and the chest wall when the lungs expand and contract during breathing.
Intraplural fluid facilitates the movement of the lungs with every inhalation and exhalation in the chest cavity. It also protects the lungs from chest traumas.
Pleural fluid is contained within the pleural space, a thin fluid-filled cavity between the two layers of the pleura (lining of the lungs and chest cavity). This space prevents the fluid from leaking into surrounding tissues. The balance between fluid production and absorption by the pleura helps maintain the fluid in this contained space.
Inflammation of the tissues that cover the lungs and line the chest cavity causes pleuritis, with fluid accumulating in the lungs.
Mediastinum
The pleural fluid reduces the friction between the lungs and the walls of the thorax by lubricating the pleural surfaces. This fluid allows the lungs to move smoothly during respiration without causing friction or resistance.
plueral space
Hi all I no is there is the chest and lungs both have walls with fluid to stop them rubbing. I no this because when I went to doctors about pain in chest he told me I've managed to lose fluid between them causing me nasty pain and them rubbing. ( it was caused by nasty cough I had and I've got it again). Hope this answers abit of your question.
pleuritis
its in the middle of your chest, between the lungs
