Mucosal Immune System

The mucosal immune system is a crucial part of our body's defenses that protects the surfaces lining organs like the intestines, lungs, and mouth. This system includes specialized immune cells and tissues that respond to germs and harmful substances encountered in these areas. It plays a vital role in distinguishing between harmful invaders and harmless substances, helping to prevent infections while maintaining tolerance to food and beneficial microbes. Essentially, it acts as a gatekeeper, ensuring our body stays healthy without overreacting to non-threatening elements.
