The mucosal barrier

The mucosal barrier is a protective layer found in various parts of the body, such as the digestive and respiratory tracts. It consists of mucus and specialized cells that form a lining to shield the underlying tissues from harmful substances like pathogens and toxins. This barrier also helps to maintain moisture and supports immune function. If the mucosal barrier is damaged or compromised, it can lead to infections or diseases. Overall, it's essential for maintaining the health of the organs it covers.
