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 a means by which the body protects itself from infection by producing antibodies that target foreign material in the bloodstream that is seen as potentially dangerous, marking it for destruction.
