Which of the following statements does NOT accurately describe a difference between the innate and adaptive defenses of the body
Sliva [168]

The incorrect statement is option (A) the innate defenses of the body apply strictly to external pathogens, while adaptive defenses apply strictly to internal pathogens.

Immunity can be classified into two types namely, the innate immunity and the adaptive immunity. Innate immunity is the first line of defense against the pathogens. It includes the physical and chemical barriers of the immune system along with the action of the phagocytizing cells called the macrophages. Whereas, the adaptive immunity is mediated by the cells of the immune system called the lymphocytes. The B lymphocytes produce antibodies and are responsible for humoral immunity. The T lymphocytes produce the cell mediated immunity with the production of the helper T cell, cytotoxic T cells and attack the pathogens. Innate immune response is comparatively a faster immune response which can be activated by any foreign substance entering the body. Both the defenses work on external and internal pathogens.
