What type of immunity is responsible for the rejection of grafts?

Step-by-step solution

The primary and secondary immune responses are carried out with the help of two special types of lymphocytes present in our blood, i.e., B-lymphocytes and T-lymphocytes.B-lymphocytes produce an army of proteins in response to pathogens in our blood to fight them. These proteins are called antibodies.Before transplantation, tissue matching and blood group matching are essential to prevent rejection of the organ. The body is able to differentiate 'self' and 'nonself' and the cell-mediated immune response is responsib
