Question

Quizplus · Accepted Answer

Innate immunity is the first line of defense against pathogens and is present at birth. It is nonspecific, meaning that it can respond to a wide range of pathogens, but does not have a memory component.

Answer A is incorrect because innate immunity is actually faster than adaptive immunity in responding to pathogens.

Answer C is incorrect because only adaptive immunity involves a memory component.

Answer D is incorrect because T cells and B cells are part of adaptive immunity, not innate immunity.

Answer E is incorrect because innate immunity provides a baseline level of protection against pathogens, and actually reduces susceptibility to disease.
