Question

Quizplus · Accepted Answer

The innate immune system is the first line of defense against pathogens, and it responds quickly and nonspecifically to any microorganism or toxin that enters the body. It includes physical barriers (such as skin), chemical barriers (such as stomach acid), and specialized immune cells (such as phagocytes). The intrinsic immune system is not a commonly used term, and the specific immune system (also called adaptive immune system) is slower to respond and targets specific pathogens based on memory from previous exposure. The native immune system is not a recognized term.
