Explanation:
Detailed explanation-1: -The lymphatic ducts empty the lymph into your subclavian veins. These veins, located below your collarbone, join to form the superior vena cava. The vena cava returns clean lymphatic fluid to your bloodstream.
Detailed explanation-2: -After collecting in the cisterna chyli, lymph flows proximally through the thoracic duct, and ultimately empties in the venous circulation at the junction of the left internal jugular and subclavian veins.
Detailed explanation-3: -Lymph from the left upper body also enters the thoracic duct. The right lymphatic duct empties the lymph into the right subclavian vein of the blood circulation, while the thoracic duct connects with the left subclavian vein.
