What cell is inhabitant of the RES? | phagocytic cell |
one of the follwoing is not part of the 2nd line of defense: (plasma cell, interferon, phagocytosis, complement) | plasma cell |

this WBC is responsible for cell mediated immunity (neutrophil, lymphocyte, monocyte, NK cell) | lymphocyte |
immunity through breast feeding (natural active, natural passive, artificial active, artificial passive) | natural passive |
developing immunity through getting exposed to a microbe (natural passive, artificial passive, natural active, artificial active) | natural active |
