Natural membranes

Natural membranes are thin, flexible layers of tissue that surround and protect organs and structures in the body. They are composed of cells and specialized tissues that form a barrier, helping to prevent infections, reduce friction, and facilitate movement. Examples include the membranes lining the lungs (pleura), heart (pericardium), and abdominal organs (peritoneum). These membranes also play roles in secretion and absorption, maintaining internal environment stability. Their structure and function are vital for overall health, ensuring organs can operate smoothly within the body’s complex system.
