The mucosal immune system

The mucosal immune system is a key part of our body's defense mechanisms, protecting us from pathogens at mucosal surfaces, like the gut, respiratory tract, and other openings. It consists of specialized cells and tissues that recognize harmful invaders, helping to prevent infections. Unlike the general immune system, which responds to threats throughout the body, the mucosal immune system is adapted to manage the unique challenges of mucosal surfaces, balancing the need to fight infections while tolerating harmless substances, such as food and beneficial bacteria. This system is crucial for maintaining overall health and well-being.
