MICROANATOMY

Detailed explanation-1: -The thoracic duct drains into to the left subclavian vein while the right duct drains into the right subclavian vein, both at the junction between the respective vein and the jugular vein. The two subclavian veins then merge into the vena cava, the large vein that brings deoxygenated blood to the heart.

Detailed explanation-2: -The various efferent lymphatic vessels in the body eventually converge to form two major lymphatic channels: the right lymphatic duct and the thoracic duct.

Detailed explanation-3: -The thoracic duct is the larger of the two and responsible for lymph drainage from the entire body except for the right sides of the head and neck, the right side of the thorax, and the right upper extremity which are primarily drained by the right lymphatic duct.[1][2] Structure and Course.
