Lower quadrants drain into which lymph nodes?

• A. Cervical
• B. Inguinal
• C. Axillary
• D. Popliteal

Answer: (B)

Lymph from the lower body tends to flow toward the groin area, so the main drainage checkpoint for the lower quadrants is the inguinal lymph nodes. These nodes, located in the groin, receive lymph from the lower limbs, lower abdomen below the umbilicus, and perineal region, and then pass it on toward deeper pelvic nodes. The popliteal nodes behind the knee handle lymph from parts of the lower leg and foot, not the entire lower quadrant, so they aren’t the primary drainage site for the lower body. Cervical and axillary nodes serve the head/neck and upper limbs respectively, not the lower body. In practice, guiding drainage toward the inguinal nodes aligns with the natural pathways for clearing lymph from the lower region.
