Lymph empties into the subclavian vein
Interstitial fluid drains from the tissues into the lymphatic system. When interstitial fluid enters the lymph vessels it becomes ‘lymph’ (lymphatic fluid). Lymph then drains back into the blood system through the left and right subclavian veins.
Adapted from the diagram 'Lymphatic Vessels, Trunks, and Ducts' by Julie Jenks, a derivative of the original work by Daniel Donnelly.
