mucosal permeability

Mucosal permeability refers to how easily substances can pass through the mucous membranes that line organs like the gut, nose, or lungs. These membranes act as barriers, allowing nutrients and essential molecules to enter the body while blocking harmful substances. When permeability is balanced, it maintains health; increased permeability, often called a "leaky" barrier, can let unwanted particles, toxins, or microbes pass through more readily. This can lead to inflammation or infections. Factors like diet, stress, or illness can influence mucosal permeability, affecting overall health and immune function.
