Which of the following is not an example of a non-specific defense mechanism?
Antibodies are produced by mature B-cells. B-cells on maturation get transformed into a specific structure having specific antigenic sites. The presence of specific antigenic sites makes them efficient enough in recognizing antigens and generates specific immune responses (antibodies). Thus, it is a component of specific or adaptive immune response.
Inflammation is a natural/ innate immune response of a body in which blood circulation is increased at the site of infection thus dilutes the toxin secreted by infecting organisms.
Mucous membrane traps the microorganisms, thus acting as the first line of defence under the physical barrier categories.
Skin is the largest organ of the human body and it also acts as a physical barrier. Further, it also is the first point of contact for any type of infection.
