In leg lymph drainage, which region is drained first to clear proximal drainage toward the trunk?

• A. Foot.
• B. Calf.
• C. Thigh.
• D. Knee.

Answer: (C)

When draining the leg toward the trunk, start with the region closest to the trunk so the central pathways are cleared first. The thigh is the most proximal segment of the leg, feeding lymph into the inguinal nodes and onward to the trunk. By addressing the thigh first, you open the main proximal channels, allowing lymph from the calf and foot to flow upward into the thigh and then toward the central lymphatic system more effectively. Starting in more distal areas like the foot or calf would push lymph into an area that isn’t yet cleared, which can slow drainage and promote pooling. The knee sits between thigh and calf but is not as proximal as the thigh, so it’s less optimal as the first region.
