So this is basically a diagram of flow chart that describes everything we just discussed. It summarizes our results, our discussion. So we have our immune system that is split into two categories. So the innate immune system that begins to act immediately after infection it involves cells like macrophages, neutrophils and so forth. And then we have our adaptive immunity that develops over some period of time because it has to synthesize the plasma cells, the memory cells, as well as other cells such as helper T cells and cytotoxic T cells. Now, adaptive immunity can be split into two.
