What receives lymph from lower limbs?

The thoracic duct itself begins just beneath the diaphragm in the cisterna chyli, a sac-like chamber that receives lymph from the lower abdomen, pelvis, and lower limbs by way of the left and right lumbar trunks and the intestinal trunk.

Where is the lymphatic system in the leg?

There are four lymphatic pathways in the lower leg (anteromedial, anterolateral, posterolateral, and posteromedial) that drain mainly to three lymph nodes; two nodes were in the superficial inguinal region and one node was in the popliteal region.

Which lymph nodes drain the lower limb?

Most of the lymph from lower limb is drained into the inguinal lymph node, either directly (mostly) or indirectly (partly) through the popliteal and tibial nodes. Note:- The deep structures of the gluteal region and upper part of the back of thigh are drained into the internal iliac nodes. LYMPH NODES:-

What’s the lymphatic system do?
