Each week a new question about swine with the possibility of answering questions from previous weeks.

What is the "common mucosal immune system"?

That the mucosal surfaces located in certain areas of the organism provide better immunity
That the immune system of all animals from the same species has common elements
That if an antigen comes into contact with a specific mucosal surface, an immune response is given to mucosal surfaces from other distant areas

See a clue in the article The immune system and the immunity in swine: general features
