Surfactant is when your mum produces something bad into the mouth of your daddy
Surfactant is pleural fluid.
Pleural fluid is the fluid that's located between the pleural membranes that cover the lungs. If too much fluid builds up, it's called a pleural effusion.
Pleural fluid is contained between the parietal pleura and chest wall.
Pleural Fluid. It is mostly made up of tissue fluidPleural spacePleural fluid
Pleural fluid is present in the pleural sac. This fluid act as a lubricant and minimizes the friction between outer and inner layer of pleura, during respiration.
Each lung lies within the pleural cavity within which the lung expands. The pleural cavity is lined by two transparent elastic membranes called the pleura/pleural membranes. The inner pleuron covers the lung the outer pleuron is in contact with the walls of the thorax and the diaphragm. A thin layer of lubricating fluid between the pleural membranes allows them to glide over each other when the lungs expand and contract during breathing. So your answer is the pleural fluid lies between the pleural membranes.
Pleural cavity is the potential space. There is no gap between the outer and the inner pleura. There is very little fluid in the pleural cavity. You have negative pressure in the pleural cavity.
Pleural biopsy is usually ordered when pleural fluid obtained by another procedure called thoracentesis (aspiration of pleural fluid) suggests infection, signs of cancer, or tuberculosis.
Pleural fluid is the fluid found in your lungs. My guess is that a pleural hemorrhage would be the result of fluid buildup expanding the lungs to the point where the tiny sacs in your lungs could rupture.
A procedure in which fluid is withdrawn from the pleural cavity through a needle inserted between the ribs
Pleural effusion is excess fluid that accumulates between the two pleural layers, the fluid-filled space that surrounds the lungs. Excessive amounts of such fluid can impair breathing by limiting the expansion of the lungs during ventilation.
this answer is pleural cavity
