Explanation:
Detailed explanation-1: -The collecting vessels merge and empty lymph into the bloodstream by way of the thoracic duct at its entry into the left subclavian vein or by the right lymphatic duct, which empties into the right subclavian vein.
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: -The thoracic duct develops from lymphatic trunks on either side of the aorta that anastomoses to form a channel from the jugular lymph sacs to the cisterna chyli.
