The popliteal lymph nodes are part of the deep inguinal lymph nodes, which drain lymph from the lower extremities, including the foot, leg, and thigh.
They are important for filtering lymph fluid and removing waste products, pathogens, and other foreign substances before the lymph fluid returns to the bloodstream.
