Explanation:
Detailed explanation-1: -Antigens are proteins that are found on the surface of the pathogen. Antigens are unique to that pathogen. The whooping cough bacterium, for example, will have different antigens on its surface from the TB bacterium. When an antigen enters the body, the immune system produces antibodies against it.
Detailed explanation-2: -Immunoglobulin A (IgA) IgA is one of the body’s first-line defenses against infection. It binds to pathogens to tag them for destruction and prevents them from sticking to the epithelium, which lines the body’s tissues.
