MICROANATOMY

Detailed explanation-1: -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-2: -Blood Supply and Lymphatics The left subclavian trunk directly drains into the thoracic duct, and the right subclavian trunk continues to form the right lymphatic duct, which enters at the right venous angle (junction of the internal jugular vein and subclavian vein).

Detailed explanation-3: -Lymphatic vessels collect and filter lymph (at the nodes) as it continues to move toward larger vessels called collecting ducts. These vessels operate very much like your veins do: They work under very low pressure, have a series of valves in them to keep the fluid moving in one direction.
