Question

Quizplus · Accepted Answer

Lymph nodes are an important part of the immune system where bacteria and other foreign particles are removed by phagocytes and the adaptive immune response is initiated. Lymphocytes do flow through lymph nodes, but they are not the only type of cells present. Therefore, lymph nodes can be a site of infection. Option A is partially correct, as lymph moves through lymph nodes in one direction, but not in two directions. Option B is incorrect, as sinuses in lymph nodes are lined by T cells, not B cells. Option D is also incorrect, as lymph nodes contain a variety of cells, not just lymphocytes.
