mucosal membranes

Mucosal membranes are thin layers of tissue that line various body cavities and organs, such as the respiratory, digestive, and reproductive systems. They produce mucus, a slippery substance that helps protect and lubricate surfaces, traps pathogens, and facilitates the movement of materials. These membranes are vital for proper function, as they act as barriers against infection and irritation, maintaining the health of the underlying tissues. Mucosal membranes also play a role in absorption and secretion, helping the body interact with its environment effectively.
