MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -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.

Detailed explanation-3: -The right lymphatic duct, near the base of your neck, collects lymph from the right side of your arm, chest and neck. The thoracic duct starts near the bottom of your spine. It collects lymph from your abdomen, lower chest and pelvis. The lymphatic ducts empty the lymph into your subclavian veins.

Detailed explanation-4: -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.
