Which of the following is true about the adaptive immune system? Check all please. Adaptive immunity develops several days after the initial infection, but eliminate pathogens in a specific manner and is saved as memory to encounter the same reinfection Adaptive immunity is improved with repeated infections with the same pathogen A robust primary adaptive immunity can be generated in the absence of innate immunity Adaptive immune cells are B cells that make antibodies and T cells that eliminate infected cells and make cytokines Dendritic cells present antigens to T cells, whereas macrophages present antigens to B cells.

Using words and arrows, complete a flow outline of an immune response, beginning with entrance of antigen; start with the response of the innate immune system, describe antigen processing, cell interaction, involvement of cytokines, and the end results for B and T cells.

True/False: Unlike innate immune responses, adaptive immune responses are initiated in secondary lymphoid organs. However, the innate immune response to an infection in a tissue has a pivotal role in inducing T-cell responses in the nearest lymph node by activating tissue dendritic cells and inducing their migration to the lymph node.
