The cell-mediated immunity inside the human body is carried out by

Step-by-step solution

T-lymphocyte receptors can recognise only antigen that bound to cell membrane proteins. These lymphocytes mediate CMI (cell mediated immunity). B-lymphocytes are the major effector molecules of humoral immunity. Erythrocytes are red blood cells. Thrombocytes or platelets secrete factors that are involved in vascular repair.
