👉 The quit fluid, also known as pleural fluid, is a clear, colorless liquid that fills the space between the lungs and the chest wall, specifically within the pleural cavity. This fluid plays a crucial role in maintaining the lungs' ability to expand and contract efficiently during breathing; it acts as a lubricant, reducing friction between the lung tissue and the chest wall as they move during inhalation and exhalation. Additionally, it helps to equalize pressure between the inside of the lungs and the outside environment, ensuring that the lungs can expand without being compressed by the chest wall. The normal amount of quit fluid is about 5-10 milliliters per chest, and any significant change in its volume can indicate underlying respiratory or cardiac conditions.
