Final answer:
The innate nonspecific immune system is a generalized defense against a variety of pathogens. It is nonspecific and does not provide long-lasting immunity.
Step-by-step explanation:
The innate nonspecific immune system is a generalized defense against a variety of pathogens. It includes multiple types of barriers to pathogens, leukocytes that phagocytize pathogens, and several other general responses. Unlike the adaptive immune system, which mounts a highly specific response to individual pathogens, the innate immune system is nonspecific and does not provide long-lasting immunity.
