How do memory cells differ from effector cells? view available hint(s)how do memory cells differ from effector cells? memory cells are responsible for the primary immune response. memory cells are more numerous. memory cells combat antigens; effector cells do not. memory cells live longer?

Th memory cells differ from the effector cells in that the memory cells live longer. Two types of cells are produced by the clonal selection, these are the effector cells and the memory cells. Effector cells are relatively short lived activated cells that defend the body in an immune response. Effector B cells are called plasma cells and secrete antibodies, and activated T cells include cytotoxic T cells and helper T cells, which carry out cell-mediated responses. The production of effector cells in response first time exposure to an antigen is called the primary immune response. The memory produced at this time and only become active in case of a re-exposure to the same antigen that stimulated their formation.
