Solution

Thanks for the question

One of the functions of specialized cells (located in the thymus and bone marrow) is to present young lymphocytes with self antigens produced throughout the body and to eliminate those cells that recognize self antigens, preventing autoimmunity.

Therefore what this means is that the body is educated on what are the normally required cells and produced in the body so that when any cells other than the known ones, eneter the bloodstream they are eliminated or any immune reaction is produced against them.

Thanks
