B cells are part of the humoral immunity (not the cell-mediated immunity). Leukocytes are any white blood cell (B cells, T cells, macrophages, granulocytes, etc.), only some of which are involved in cell-mediated immunity.
Humoral immunity is called active when the organism generates its own antibodies, and passive when antibodies are transferred between individuals or species. Similarly, cell mediated immunity is active when the organismsâ own T-cells are stimulated, and passive when T cells come from another organism.
