GENERAL HISTOLOGY

Detailed explanation-1: -Vascular System Lymph from the right side of the head, right trunk, and right arm drains into the right lymphatic duct. Lymph from the remainder of the body drains into the thoracic duct, which empties into the thoracic vena cava.

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: -Collecting ducts: Lymphatic vessels empty the lymph into the right lymphatic duct and left lymphatic duct (also called the thoracic duct). These ducts connect to the subclavian vein, which returns lymph to your bloodstream. The subclavian vein runs below your collarbone.
