Quizplus · Accepted Answer

B cells differentiate in the bone marrow and then migrate into the bloodstream. From there, they travel to lymph nodes where they can encounter antigens and activate into effector B cells or differentiate into memory B cells. Therefore, the correct sequence of migration is bone marrow → blood circulation → lymph nodes.
