Document Summary
Stem cells of wbcs lack an enzyme that allows them to fight. Leukemia: infection: group of cancers, affect white blood cells in which these cells proliferate without control. Infectious mononucleosis: also known as the kissing disease , occurs when the epstein-barr virus (ebv) infects lymphocytes resulting in: Arise through fragmentation of large cells: megakaryocytes. Create clots by forming fibrin threads that catch red blood cells. 2) platelets congregate and form a plug. 3) platelets and damaged tissue cells release prothrombin activator. 4) fibrin threads form: trap red blood cells. Antibody: a protein made in response to an antigen in the body. Presence and/or absence of 2 blood antigens: a, b. Antibodies are only present for those antigens lacking on the cells because: proteins recognize. Bind the protein they are named after. Blood types are named after the protein antigens that are present on the surface of the rbcs.
