Question

Quizplus · Accepted Answer

Lymph nodes are sites of mechanical filtering, where immune cells called lymphocytes and macrophages remove foreign particles, such as bacteria, viruses, and cancer cells, from the lymph fluid that drains from the surrounding tissues. Inflammation can occur in lymph nodes as a result of infection or injury, but they do not directly regulate blood fluid and do not serve as sites of new cell entry.
