Detailed explanation-1: -The process where these white blood cells surround, engulf, and destroy foreign substances is called phagocytosis, and the cells are collectively referred to as phagocytes.
Detailed explanation-2: -T Cells Recognize Foreign Peptides Bound to MHC Proteins As discussed earlier, both cytotoxic T cells and helper T cells are initially activated in peripheral lymphoid organs by recognizing foreign antigen on the surface of an antigen-presenting cell, usually a dendritic cell.
Detailed explanation-3: -T lymphocytes T cells have three main jobs: They use chemical messengers to activate other immune system cells in order to start the adaptive immune system (T helper cells). They detect cells infected by viruses or tumorous cells and destroy them (cytotoxic T cells).
