Trapping particles for immune cells to destroy.
Lymph nodes contain a reticular network, macrophages and dendritic cells that trap pathogens and debris brought in by afferent lymph. Those antigen-presenting cells and resident lymphocytes then phagocytose pathogens and activate adaptive immune responses (B cells, T cells). The other choices are inaccurate: nodes don’t simply chemically neutralize all toxins, act as a pore filter, or send lymph directly to the heart.
