a: Humoral immunity ~
b: front line troops
What:
"Humoral immunity is like the front line troops that work outside the cellular fortress: it is the first line of defense. Humoral immunity occurs in the body fluids where B cells float around on sentry duty. When B cells come into contact with antigens (proteins from a virus), they activate antibodies which they carry on their back. "
