Summary

Description
English: Memory B cell response on first, and second infections of a virus.

1. Antigens from the virus are brought into the body, and are then accepted by the receptors on the B cells.
2. The B cells accept the antigens, and then start to allow the antigens to change the antibodies and the B cell.
3. The B cells either change into memory B cells, or create plasma cells that secrete the newly changed antigens. 4. On the second infection when that same viruses antigens are present the memory B cells recognize this virus. This causes a much larger response from these memory B cells compared to the first response of the B cells

5. Since there was a much larger response from the Memory B cells this causes more plasma cells to be produced as a response. When there are more abundant plasma cells, more antibodies are then produced as a result of this.
