quizlet define explain the difference between innate(nonspecific) immunity and adaptive (specific) immunity
What is the difference between Innate Immunity and Adaptive Immunity? â¢ The innate immune system is composed of physical and chemical barriers, phagocytic leukocytes, dendritic cells, natural killer cells, and plasma proteins whereas the adaptive immune system is composed of B cells and T cells.
The cells of the innate system recognize and respond to pathogens in a generic way, but, unlike the adaptive immune system, the system does not provide long-lasting immunity to the host. Innate immune systems provide immediate defense against infection, and are found in all classes of plant and animal life.
