Quizplus · Accepted Answer

When a person's immune system is activated in response to an infection, T cells are produced and travel via the lymphatic system to the lymph nodes in the region of the infection. This causes the lymph nodes to become enlarged as they work to activate and coordinate the immune response. Therefore, the physical sign that a person's immune system is involved in the proliferation of T cells in response to an infection is the enlargement of lymph nodes in the region of the infection.
