Ordering: Put these steps of an allergic response in the right order:
________________________you sneeze
________________________Mast cells produce histamines that vasodilate lymph and blood vessels
________________________you are exposed a second time to the antigen
_________________________antibodies bind to mast cells
_________________________helper T-cells produce IL-4 (interleukin 4)
_________________________you are first exposed to an allergen
