mucosal surfaces

Mucosal surfaces are thin layers of tissue lining various body cavities and organs, such as the mouth, nose, digestive tract, and respiratory system. They serve as protective barriers, helping to trap pathogens and particles while facilitating the absorption of nutrients and moisture. Mucosal surfaces are coated with mucus, which keeps them moist and serves as a defense mechanism against infections. They also contain specialized cells that play roles in immune responses, helping to protect the body from harmful substances. Overall, they are essential for maintaining health and preventing disease.
