Quizplus · Accepted Answer

Memory cells are a special type of immune cell that is generated when the immune system encounters an antigen for the first time. These cells are "programmed" to remember the antigen and can respond more quickly and effectively if the same antigen is encountered again in the future. This allows the immune system to mount a faster and stronger response, which can help to prevent certain diseases or infections from taking hold.
