👉 The heath fluid, also known as pleural fluid, is a clear, colorless liquid found in the space between the lungs and the chest wall, known as the pleural cavity. It serves a crucial role in maintaining the lungs' ability to expand and contract during breathing. The fluid's primary function is to reduce friction between the lung tissue and the chest wall, allowing for smooth and efficient lung movement. It also helps distribute pressure evenly across the lungs, ensuring that air can enter and exit the alveoli effectively. The balance of this fluid is vital; too much or too little can lead to respiratory complications such as pleural effusion, where excess fluid accumulates, or pleural effusion with low protein content, known as ascites, which can impair lung function.
