Mucosal immunity: The immune system's defense mechanisms at the body's mucous membranes, like in the gut.
Gut-associated lymphoid tissue (GALT): The immune tissue located in the digestive tract, crucial for gut health.
Oral tolerance: The immune system's ability to not react to harmless substances ingested through the mouth.
