MICROANATOMY

Detailed explanation-1: -The thoracic duct occasionally divides into a right and left duct, with the left entering the venous system as normal, and the right draining into the right subclavian vein. The duct may also drain into the left internal jugular vein, or into the left brachiocephalic vein.

Detailed explanation-2: -The thoracic duct and right lymphatic duct are two major lymph channels found close to the posterior thoracic wall. The thoracic duct commences at the L1/L2 level, anterior and slightly to the right of the vertebral bodies and travels about 38 to 45 cm to the base of the neck in adults.
