Explanation:
Detailed explanation-1: -The thoracic duct is the largest lymphatic vessel in the human body. Around 75% of the lymph from the entire body (aside from the right upper limb, right breast, right lung and right side of the head and neck) passes through the thoracic duct.
Detailed explanation-2: -The pre-and para-aortic lymphatics drain into the cisterna chyli which is an elongated sac-like vessel that lies over the body of L1 and L2 behind the inferior vena cava and between the aorta and the azygous vein. It becomes the thoracic duct as it ascends through the diaphragm at the level of T12.
