List the players in the humoral immune system .?

Answer 1

Nope, the above answer is only partially correct. T-cells are part of the cell-mediated immune system. B-cells and their differentiated forms--plasma cells and memory cells--are part of the humoral immune system, which includes the antibodies as produced by plasma cells and memory cells for anamnestic (memory) secondary response to an antigen.

Hope this helps!

Answer 2

Primarily T-cells and B-cells.
